## Homework Statement

Determine the RMS value of fullwave rectified sine wave.

## Homework Equations

RMS = [tex]\sqrt{({1}/{b-a})\int^{b}_{a}[(fx)]^{2}dx}[/tex]

## The Attempt at a Solution

Notes: The Period of a full wave rectified sine wave is pi.

a=0

b=pi

Let's do square root at the end.

=[tex]1/pi \int^{pi}_{0}sin^{2}xdx[/tex]

=1/pi [pi/2 - [sin(2pi)]/4] - 1/pi [pi/2 - [sin(2pi)]/4]

=1/2 - 1/2 ? ? ? ? ? ?

Where am i going wrong? Sorry I am not good with latex code, even with the reference.
