Homework Statement
A generated AC voltage has a value given by V = 4cos2θ.
You will need to use the identity cos^2θ = 1/2(1+cos2θ)
Homework Equations
a) Find the mean value of the voltage over a full cycle (0 ≤ θ ≤ 2π) using integral calculus
b) Find the r.m.s. value of the voltage over a full cycle (0 ≤ θ ≤ 2π) using integral calculus
The Attempt at a Solution
How should I be able to solve problems like this?
