V= 100sin(100*Pi*t) + 60sin(300*pi*t - Pi/2) + 30sin(600*pi*t + pi/2)

I need to find the:

-Amplitude of Fundamental

-Frequency of Fundamental

-Amplitude of Harmonic components

-The Phase Angle

-The Instantaneous Value of v 5.12 ms from the start of cycle.

As I understand each element from the expression is equivalent to a value above (?) or do I have to break the expression up?
