Find Amplitude of Sine and Cosine

[nycmathguy]

Section 4.5

Let me see.

Given y = a sin x and y = a cos x, the
Amplitude = | a |.

Question 6

A = | 3 | = 3

Question 8

A = | - 5 | = 5

Question 10

A = | 1/4 | = 1/4

Question 12

A = | -2/5 | = 2/5

question says, find the period and amplitude

I decided to divide the question into two parts.
