First and foremost, I would like to thank Allah for the energy and determination to do this
project. Next, my Additional Mathematics teacher,Mr. Faizal as he gies us consistent guidance
during this project work. !e has "een a ery supportie figure throughout the whole project.
I also would like to gie thanks to all my friends for helping me and always supporting me to
complete this project work. #hey hae done a great jo" at proiding different referenceand

Introduction
In mathematics, the maximum and minimum of a function,known collectiely asextrema are the largest and smallest alue that the function takes at a point either within a gien
neigh"ourhood *local or relatie extremum+ or on the function domain in its entirety *glo"al or
a"solute extremum+. ierre de Fermat was one of the first mathematicians to propose a generaltechni&ue *called ade&uality+ for finding maxima and minima. #o locate extreme alues is the
"asic o"jectie of optimization.
%inear programming started when Fermatand %agrangefound calculus("ased formulas
for identifying optima, whileNewtonand-aussproposed iteratie methods for moing towards
an optimum. #he term linear programming for certain optimization cases was due to -eorge /.
0antzig, although much of the theory had "een introduced "y %eonid 1antoroich in 2343.*rogramming in this context does not refer to computer programming, "ut from the use of
program "y the 5nited 6tates military to refer to proposed training and logisticsschedules, which
were the pro"lems 0antzig studied at that time.+ 0antzig pu"lished the 6implex algorithm in2378, and 9ohn on Neumanndeeloped the theory of dualityin the same year.

i. Mathematical optimization deals with the pro"lem of finding numerically minimums *ormaximums or zeros+ of a function. In this context, the function is called cost function, or
o"jectie function, or energy.It is a "ranch of mat%ematicsthat focuses on pro"lems
where scarce resources need to "e allocated effectiely, in complex, dynamic and
uncertain conditions. #he program com"ines a solid foundation in math with specialse&uences of courses in economics, "usiness, and management science. In the simplest
case, an optimization pro"lem consists of maximizingor minimizing a real function"y
systematically choosing inputaluesfrom within an allowed set and computingthe alueof the function. #he generalizationof optimization theory and techni&ues to other
formulations comprises a large area of applied mathematics. More generally, optimization
includes finding "est aaila"le alues of some o"jectie function gien a defineddomain*or a set of constraints+, including a ariety of different types of o"jectie
functions and different types of domains.
ii. In mathematical analysis, the maxima and minima *the plural of maximum and
minimum+ of a function, known collectiely as extrema *the plural of extremum+, are the
largest and smallest alue of the function within the entire domain of a function *the
glo"al or a"solute extrema+.
$e say that f*x+ has an a"solute *or glo"al+ maximum at x:c if f*x+ ; f *c+ for eery x in
the domain we are working on. $e say that f*x+ has an a"solute *or glo"al+ minimum at
x:c if if f*x+ < f *c+ for eery x in the domain we are working on.
iii. In mathematical analysis, the maxima and minima *the plural of maximum and
minimum+ of a function, known collectiely as extrema *the plural of extremum+, are the
largest and smallest alue of the function, within a gien range *the local or relatie
extrema+
$e say that f*x+ has a relatie *or local+ maximum at x:c if f*x+ ; f *c+ for eery x in
some open interal around.
$e say that f*x+ has a relatie *or local+ minimum at x:c if f*x+ < f *c+ for eery x insome open interal around.

practical pro"lems in operations researchcan "e expressed as linear programming
pro"lems. ertain special cases of linear programming, such as network flowpro"lemsand multicommodity flowpro"lems are considered important enough to hae generated
much research on specialized algorithms for their solution. A num"er of algorithms for

!istorically, ideas from linear programming hae inspired many of the central concepts
of optimization theory, such as duality,decomposition,and the importance
of convexityand its generalizations. %ikewise, linear programming is heaily usedinmicroeconomicsand company management, such as planning, production,
transportation, technology and other issues. Although the modern management issues are
eer(changing, most companies would like to maximize profits or minimize costs withlimited resources. #herefore, many issues can "e characterized as linear programming
pro"lems.
#he example of its uses in a daily life includes G rew 6cheduling
i+ Make sure that each flight is coered
ii+ Meet regulations, eg' each pilot can only fly a certain amount each dayiii+ Minimize costs, eg' accommodation for crews staying oernight out of towns,
crews deadheading
i+ $ould like a ro"ust schedule. #he airlines run on small profit margins, so saing a
few percent through good scheduling can make an enormous difference in termsof profita"ility. #hey also use linear programming for yield management

IJe found a lot of information while conducting this Additional Mathematics project. IJe learnt
the uses of function in our daily lies. I neer thought addmaths could "e used this wayK
#hroughout this project, I hae learned that hardwork is the key to success. My hardships in
doing this project has made me realized that challenges can turn into something "etter. As a
change, I hae came to understand this topic "etter.
I hae also tightened the "onds "etween myself, my instructor and my friends through this
project. $e should always offer help to anyone who asks. I also o"tained a "rand new thinking
skill and can practice effectie mathematical communication thanks to this project work.
In a nutshell, I think this project teaches a lot of moral alues, and also tests the studentsJ
understanding in Additional Mathematics. %et me end this project with a modified lyrics to 9asonMrazJs song, Make it mineL
$ake up eeryone
!ow can you sleep at a time like this
unless youJre gonna score A plus
%isten to his oice,
#he man who teach eerything from just the tip of his thum"s
Making his students understand.
IJm not gonna waste these times
As they are precious
#he success is guaranteed
