Find the period and amplitude y 8 sin 3x period amplitude F

Find the period and amplitude. y = 8 sin 3x period amplitude Find the period and amplitude. y = 8 cos 4x period amplitude Find the period and amplitude. y = 3/4 cos x/2 period amplitude Find the period and amplitude. y = -7 sin x/4 period amplitude

Solution

5)   y = 8*sin3x

Period = 2pi/3

Amplitude = 8

6)   y = 8*cos4x

Period = pi/2

Amplitude = 8

7)   y = (3/4)*cos(x/2)

Period = 4pi

Amplitude = ¾

8)   y = -7*sin(x/4)

Period = 8pi

Amplitude = 7
