Question

Write equations for the waveforms of Figure. Express the phase angle in
degrees. 

Here the answers that I did:

(a) i(t)

I(t) = 5sin(1000t + 36o)mA


(b) i(t) (t = 50ms is period of waveform b.)

i(t) = 10sin(125.66t + 60o)A

(c)  v(t) 

40sin(5655t - 45o)V

can you check if my answer is correct?
