Computing the Values of Trigonometric Functions of
Acute Angles
Section 3.3
Objectives• Find the exact values of the trigonometric
functions of π/4 (45°).• Find the exact values of the trigonometric
functions of π/6 (30°) and π/3 (60°).• Use a calculator to approximate the values
of the trigonometric functions of acute angles.
• Model and solve applied problems involving right triangles.
sin cos tan =
csc = sec = cot =
sin cos tan =
csc = sec = cot =
sin cos tan =
csc = sec = cot =
Using a Calculator
• Make sure that the calculator is set in the correct mode.– When working with triangles, the calculator
should be set to degrees.– When working with circles, the calculator
should be set to radians.• Round the values to the indicated
number of decimal places.
