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.
