Problem #1
Find the average value and RMS value (also known as its effective DC value) of the sinusoidal voltage v(t) = VMcos(ωt). Use the mathematical definitions of average and RMS value.

Refer to table of integrals; apply “RMS” in reverse order (Square the waveform, find its Mean value, then take the square Root)
