E. Trigonometric Function Graph

1. Trigonometric function
Functions ( ) = sin , ( ) = cos , and are some
examples of trigonometric functions. The trigonometric

function maps the size of the angle to a specific valueℎ( ) =
tan
2. Maximum Value, Minimum Value, Amplitude, and

Trigonometric Function Graph Period
Some graphs of trigonometric functions are sinusoidal as

follows.
Y

period
← maximum value

← Amplitude

X

= ( ) ← Amplitude

← minimum value

a. The maximum value is the highest value of a graph at a
given interval.

b. The minimum value is the lowest value of a graph at a
given interval.

c. Amplitude is half of the distance between the minimum
value and the maximum value of a graph.

d. Period is the magnitude of the interval a graph will repeat
in the same shape.

The maximum, minimum, amplitude and chart period values of
trigonometric functions are presented in the following table.
