Introduction of Scientific calculator

5/32

A scientific calculator is a type of electronic calculator, usually but not always handheld,designed to calculate problems in science (especially physics), engineering, and mathematics.They have almost completely replaced slide rules in almost all traditional applications, and arewidely used in both education and professional settings.

In certain contexts such as higher education, scientific calculators have been superseded by

graphing calculators, which offer a superset of scientific calculator functionality along with theability to graph input data and write and store programs for the device. There is also someoverlap with the financial calculator market.

In the past, mechanical clerical aids such as abaci, comptometers, Napier's bones, books ofmathematical tables, slide rules, or mechanical adding machines were used for numeric work.This semi-manual process of calculation was tedious and error-prone.

Modern calculators are electrically powered (usually by battery and/orsolar cell) and vary from

cheap, give-away, credit-card sized models to sturdy adding machine-like models with built-inprinters. They first became popular in the late 1960s as decreasing size and cost of electronicsmade possible devices for calculations, avoiding the use of scarce and expensive computerresources. By the 1980s, calculator prices had reduced to a point where a basic calculator wasaffordable to most. By the 1990s they had become common in math classes in schools, with theidea that students could be freed from basic calculations and focus on the concepts.

Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and calculator functions are included in almost all PDA-typedevices (save a few dedicated address book and dictionary devices).

Most calculators contain the following buttons: 1,2,3,4,5,6,7,8,9,0,+,-,, (/),.,=,%, and (+/-).Some even contain 00 and 000 buttons to make larger calculations easier to compute.

HistoryThis article needs reorganization to meet Wikipedia's quality standards. There is

good information here, but it is poorly organized; editors are encouraged to be bold

and make changes to the overall structure to improve this article

Casio produced the world's first graphic calculator, the fx-7000G, in 1985. After Casio, HewlettPackard followed shortly in the form of the HP-28C. This was followed by the HP-28S (1988),

HP-48SX (1990), HP-48S (1991), and many other models. Recent models like the current HP50g (2006), feature a computer algebra system (CAS) capable of manipulating symbolicexpressions and analytic solving. The HP-28 and -48 range were primarily meant for theprofessional science/engineering markets; the HP-38/39/40 were sold in the high school/collegeeducational market; while the HP-49 series cater to both educational and professional customersof all levels. The HP series of graphing calculators is best known for its Reverse Polish notationinterface, although the HP-49 introduced a standard expression entry interface as well.

Texas Instruments has produced graphing calculators since 1990, the oldest of which was the TI-81. Some of the newer calculators are similar, with the addition of more memory, fasterprocessors, and USB connection such as the TI-82, TI-83 series, and TI-84 series. Other models,designed to be appropriate for students 1014 years of age, are the TI-80 and TI-73. Other TIgraphing calculators have been designed to be appropriate for calculus, namely the TI-85, TI-86,

TI-89 series, and TI-92 series (TI-92, TI-92 Plus, and Voyage 200). TI offers a CAS on the TI-89, TI-Nspire CAS and TI-92 series models with the TI-92 series featuring a QWERTY keypad.TI calculators are targeted specifically to the educational market, but are also widely available tothe general public.

Graphing calculators are also manufactured by Sharp but they do not have the onlinecommunities, user-websites and collections of programs like the other brands.

Origin: the abacus

The first calculators were abathia, and were often constructed as a wooden frame with beadssliding on wires. Abathias were in use centuries before the adoption of the written Arabicnumerals system and are still used by some merchants, fishermen and clerks in Africa, Asia, andelsewhere.

The first scientific calculator that included all of the basic features above was the programmableHewlett-PackardHP-9100A,[1]released in 1968, though the Wang LOCI-2 and the Mathatronics

Mathatron had some features later identified with scientific calculator designs. The HP-9100series was built entirely from discrete transistorlogic with no integrated circuits, and was one ofthe first uses of the CORDIC algorithm for trigonometric computation in a personal computingdevice, as well as the first calculator based onreverse Polish notation entry. HP became closelyidentified with RPN calculators from then on, and even today some of their high-end calculators

(particularly the long-lived HP-12C financial calculator and the HP-48 series of graphingcalculators) still offer RPN as their default input mode due to having garnered a very large cultfollowing.

Texas Instruments, after the introduction of several units with logarithm/exponent capability,came out with the first modern handheld scientific calculator in 1974 in the form of the SR-50.[2]

TI continues to be a major player in the calculator market, with their long-runningTI-30 seriesbeing one of the most widely used scientific calculators in classrooms.

Casio andSharp have also been major players, with Casio's FX series (beginning with the CasioFX-1 in 1972) being a very common brand, used particularly in schools. Casio is also the #3[citationneeded]

player in the graphing calculator market, and was the the first company to produce one(Casio fx-7000G).

Functions

Modern scientific calculators generally have many more features than a standard four or five-function calculator, and the feature set differs between manufacturers and models; however, thedefining features of a scientific calculator include:

Scientific notation for calculating large numbers floating point arithmetic logarithmic functions, using both base 10 and base e trigonometry functions (some including hyperbolic trigonometry) exponents and roots beyond the square root quick access to constants such aspi and e

In addition, high-end scientific calculators will include:

hexadecimal,binary, and octal calculations, including basic Booleanmath complex numbers fractions statistics andprobabilitycalculations programmability see Programmable calculator equation solving calculus

While most scientific models have traditionally used a single-line display similar to traditionalpocket calculators, many of them have at the very least more digits (10 to 12), sometimes withextra digits for the floating point exponent. A few have multi-line displays, with some recent

models from Texas Instruments, Casio, Sharp, and Canon using dot matrix displays similar tothose found ongraphing calculators.

Uses

Scientific calculators are used widely in any situation where quick access to certain mathematicalfunctions is needed, especially those such as trigonometric functions that were once traditionallylooked up in tables; they are also used in situations requiring back-of-the-envelope calculationsof very large numbers, as in some aspects ofastronomy,physics, and chemistry.

They are very often required for math classes from the junior high school level through college,and are generally either permitted or required on many standardized tests covering math andscience subjects; as a result, many are sold into educational markets to cover this demand, andsome high-end models include features making it easier to translate the problem on a textbookpage into calculator input, from allowing explicit operator precedence using parentheses toproviding a method for the user to enter an entire problem in as it is written on the page using

simple formatting tools.

Formula calculator

A formula calculator is a software calculator that can perform a calculation in two steps:

1. Enter the calculation by typing it in from the keyboard.

2. Press a single button or key to see the final result

This is unlike button-operated calculators, such as the Windows Calculator or the Mac oscalculator, which require the user to perform one step for each operation, by pressing buttons tocalculate all the intermediate values, before the final result is shown.

In this context, a formula is also known as an expression, and so formula calculators may be

called expression calculators. Also in this context, calculation is known as evaluation, and sothey may be called formula evaluators, rather than calculators.

How they work

Formulas As they are commonly written use infix notation forbinary operators, such as addition,multiplication, division and subtraction. This notation also uses:

Parentheses to enclose parts of a formula that must be calculated first.

In the absence of parentheses, operator precedence, so that higher precedence operators, such asmultiplication, must be applied before lower precedence operators, such as addition. Forexample, in 2 + 3*4, the multiplication, 3*4, is done first.

Among operators with the same precedence, associativity, so that the left-most operator mustbe applied first. For example, in 2 - 3 + 4, the subtraction, 2 - 3, is done first.

Also, formulas may contain:

Non-commutative operators that must be applied to numbers in the correct order, such as

subtraction and division.

The same symbol used for more than one purpose, such as - for negative numbers andsubtraction.

Once a formula is entered, a formula calculator follows the above rules to produce the final resultby automatically:

Analysing the formula and breaking it down into its constituent parts, such as operators,numbers and parentheses.

Finding both operandsof each binary operator.

Working out the values of these operands.

Applying the operator to these values, in the correct order so as to allow for non-commutativeoperators.

Evaluating the parts of a formula in parentheses first.

should be entered as

(2 + 3)/(4 - 5)

Also, the symbol is often used for division, as in

2 3

This symbol is not available on most computer keyboards, so this division operation is enteredusing the forward slash, as above.

Exponentiation

Exponentiation, or raising to a power, is often represented using a superscript. For example:

2.452

means 2.45squared.

With the limitations of a computer keyboard, in some software packages, such as MicrosoftExcel, this is entered using the caret, ^:

2.45^2

but two asterisks are also used:

2.45**2

Exponentiation and functions

When using functions, the superscript is sometimes placed immediately after the function name.For example, it is common to write the trigonometric version ofPythagoras Theorem (List oftrigonometric identities) as:

sin2(x) + cos2(x) = 1

In this identity,

sin2(x)

means the square of sin(x), and is the same as:

sin(x)2

So, for x = 3.25, it could be entered into a formula calculator that uses the caret forexponentiation as:

8/7/2019 D3802B38 NAVEEN

13/32

sin(3.25)^2

Square roots

Square roots are often specified using the symbol, but with the limitations of a keyboard this is

can be entered by using exponentiation. For example, the square root of 2:2

could be entered as:

2^(1/2)

The parentheses specify that the division should be done first.

Other roots

All roots can be specified in this way. For example, the cube root of 2 can be entered as:

2^(1/3)

Herons formula example

An example that illustrates these features isHerons formula.

One version of the formula, for a triangle with sides of length a, b and c, is equivalent to, usingsymbols that are available on a keyboard:

1/2*(a^2*c^2 - (a^2 + c^2 - b^2)/2)^0.5

For a = 2.5, b = 3.6 and c = 1.9, it could be entered into a formula calculator as:

1/2*(2.5^2*1.9^2 - (2.5^2 + 1.9^2 - 3.6^2)/2)^0.5

Types of calculator

The formula calculator concept can be applied to all types of calculator, including arithmetic,scientific, statistics, financial and conversion calculators.

The calculation can be typed or pasted into an edit box of:

A software package that runs on a computer, for example as a dialog box.

An on-line formula calculator hosted on a web site.

It can also be entered on the command line of a programming language.

Related software packages

Although they are not calculators in themselves, because they have a much broader feature set,many software tools have a formula-calculation capability, in that a formula can be typed in andevaluated. These include:

Spreadsheets, where a formula can be entered to calculate a cells content.

Databases, where a formula can be used to define the value of a calculated field in a record.

Declarative and imperative tools

Button-operated calculators are imperative, because the user must provide details of how thecalculation has to be performed.

On the other hand, formula calculators are more declarative because the typed-in formulaspecifies what to do, and the user does not have to provide any details of the step-by-step orderin which the calculation has to be performed.

Declarative solutions are easier to understand than imperative solutions, and so there has been along-term trend from imperative to declarative methods. Formula calculators are part of thistrend.

Many software tools for the general user, such as spreadsheets, are declarative. Formulacalculators are examples of such tools.

Hybrid calculators

There are hybrid calculators that combine typed-in formula and button-operated calculation. Forexample:

Calculations can be entered entirely from the keyboard, or operations can be applied to typed-innumbers or formulas using buttons, in the same calculator.

Formulas can be constructed using buttons, rather than being entered from the keyboard.

Formula copies of button-operated calculations can be created, saved and re-loaded for

application to different numbers.

Concerns on usage

In education

In most countries, students use calculators for schoolwork. There was some initial resistance tothe idea out of fear thatbasic arithmetic skills would suffer. There remains disagreement aboutthe importance of the ability to perform calculations "in the head", with some curricularestricting calculator use until a certain level of proficiency has been obtained, while othersconcentrate more on teaching estimationtechniques and problem-solving. Research suggests thatinadequate guidance in the use of calculating tools can restrict the kind of mathematical thinkingthat students engage in.] Others have argued that calculator use can even cause core mathematicalskills to atrophy, or that such use can prevent understanding of advanced algebraic concepts.

There are other concerns - for example, that a pupil could use the calculator in the wrong fashionbut believe the answer because that was the result given. Teachers try to combat this byencouraging the student to make an estimate of the result manually and ensuring it roughly

agrees with the calculated result. Also, it is possible for a child to type in 1 1 and obtain thecorrect answer '1' without realizing the principle involved. In this sense, the calculator becomes acrutch rather than a learning tool, and it can slow down students in exam conditions as theycheck even the most trivial result on a calculator.

Other

Scientific calculator displays of fractions and decimal equivalents

Errors are not restricted to school pupils. Any user could carelessly rely on the calculator's outputwithout double-checking the magnitude of the result i.e., where the decimal point ispositioned. This problem was all but nonexistent in the era ofslide rules and pencil-and-paper

calculations, when the task of establishing the magnitudes of results had to be done by the user.In addition, algorithmic flaws and rounding techniques can sometimes lead to minor precisionerrors.

Some fractions such as 23 are awkward to display on a calculator display as they are usuallyrounded to 0.66666667. Also, some fractions such as 17 which is 0.14285714285714 (to fourteensignificant figures) can be difficult to recognize in decimal form; as a result, many scientificcalculators are able to work in vulgar fractions and/ormixed numbers.

Calculators and calculation applications of computers

Personal computers andpersonal digital assistants can perform general calculations in a varietyof ways:

Most computer operating systems, at least those that support some kind ofmultitasking,include calculator programs, both text mode (such as the Unixbc (1) language) andgraphical mode (Mac OS Calculator, Microsoft Calculator,KCalc, Grapher,ATCalc).

Most, though not all, imitate the interface of a physical calculator. Some shell programsand interpreted programming languages also provide interactive calculation functions.

For more complex calculations requiring large amounts of organized data, spreadsheet programs such as Excel orOpenOffice.org Calc provide calculation and sometimesreporting functions.

Computer algebra programs such as Mathematica, and others can handle advancedcalculations.

Client-side scripting can be used for calculations, e.g. by entering

"javascript:alert(1337*7331)" in a web browser's address bar (as opposed to"http://website name"). Such calculations can be embedded in a separate Javascript orHTML file as well.

Online calculators such as thecalculator feature of the Google search enginecan performcalculations server-side.

Calculating vs. computing

The fundamental difference between calculators and computers is that computers can beprogrammed to perform different tasks while calculators are pre-designed with specific functionsbuilt in, for example addition, multiplication, logarithms, etc. While computers may be used tohandle numbers, they can also manipulate words, images or sounds and other tasks they havebeen programmed to handle. However, the distinction between the two is quite blurred; somecalculators have built-in programming functions, ranging from simple formula entry to fullprogramming languages such as RPL orTI-BASIC. Graphing calculators in particular can, alongwith PDAs, be viewed as direct descendants of the 1980s pocket computers, essentiallycalculators with full keyboards and programming capability.

The market for calculators is extremely price-sensitive, to an even greater extent than the

personal computer market; typically the user desires the least expensive model having a specificfeature set, but does not care much about speed (since speed is constrained by how fast the usercan press the buttons). Thus designers of calculators strive to minimize the number of logicelements on the chip, not the number of clock cycles needed to do a computation.

For instance, instead of a hardware multiplier, a calculator might implement floating pointmathematics with code in ROM, and compute trigonometric functions with the CORDICalgorithm because CORDIC does not require hardware floating-point. Bit serial logic designs are

more common in calculators whereasbit parallel designs dominate general-purpose computers,because a bit serial design minimizes thelanguages chip complexity, but takes many more clockcycles. (Again, the line blurs with high-end calculators, which use processor chips associatedwith computer and embedded systems design, particularly the Z80, MC68000, and ARMarchitectures, as well as some custom designs specifically made for the calculator market.)
