문제 3

Find the amplitude of the given function and plot it along with y = cos x on the same rectangular coordinate system for the domain of x from 0 to 2π.
y = 13cos x

A = 13

Graph of y = 13cos x and y = sin x from 0 to 2π with key points marked.

A = 13

Graph of y = 13cos x and y = sin x from 0 to 2π with key points marked.

A = 3

Graph of y = 3sin x and y = cos x from 0 to 2π with key points marked.

A = -3

Graph of y = 3sin x and y = cos x from 0 to 2π with key points marked.
