Hi friends
i want to prove this(in case of polyphase rectifier)

in period of [(Pi/2)-(Pi/q) _ (Pi/2)-(Pi/q)]
what i have tried

but i did not get the desired result
please help to prove it

 

Before proving it, did you check that it is possibly true? For example, what if you set w=1 and t=0 on the left, in which case the left-hand-side is zero, do you also get zero on the right-hand-side?

 

I just the other day became a member, and came to this thread because I'm trying to do a similar analysis by Fourier Transform. Did you ever reach a conclusion concerning your proof? I'll endeavor to copy your calculation in order to study it and try various things with it (I just can't concentrate when reading from a computer screen). Meanwhile, I'm hoping someone else comments - or starts a new discussion so related. I'll, of course, search the rest of this Math segment, too.
