Indicate the amplitude |A|, frequency `omega` initial phase `omega' and ` period T of the following harmonics:
(a) `f(x)=5 sin 4x`, (b) `f(x)=4 sin (3x+pi//4)`
(c) `f(x)=3 sin (x//2)+4 cos(x//2)`

Text Solution

Verified by Experts

The correct Answer is:
(a) `|A|=5, omega=4 omega=0, T=pi/2 ;` (b) `|A|=4, omega =3, omega =pi/4, T=(2pi)/(3); (c) |A|=5, omega=1/2, omega=arc tan ""4/3, T=4pi`
