Question

A generated AC voltage has a value given by V = 4cos2θ.

You will need to use the identity cos^2⁡@(〖θ= 1/2(1+cos2θ)〗
Find the mean value of the voltage over a full cycle (0 ≤ θ ≤ 2π) using integral calculus

Find the r.m.s. value of the voltage over a full cycle (0 ≤ θ ≤ 2π) using integral calculus

Answer 1

anybody?

Answer 2

?

Answer 3

do you know rms voltage

Answer 4

if that is a bit difficult. could you help me with this questions. thanks
