A trigonometric identity is an equation that is true for all values of the variable for which the expressions
on both sides of the equation are dened.
To prove that an equation is an identity, start with th

TRANSFORMATIONS OF SINE AND COSINE FUNCTIONS
AMPLITUDE
The amplitude of the functions y =a sine and y = a cost) is given by |a|. |a| = :-,
where M is the maximum value and m is the minimum value.
EXAMPLES: (Using the sine function.)
a) y = 3 sine
