I wasn't really sure where to post this because I am covering this in 2 classes (Math and Physics). Figured this would be my best bet.(adsbygoogle = window.adsbygoogle || []).push({});

The fourier series of some Function is [itex]a_{0}/2+etc...[/itex]. I've looked in several textbooks but none explain why the [itex]1/2[/itex] is there, and not in any of the other terms of the summation.

I do have a homework problem concerning this, but my professor said it's ok to not explain this part of the Fourier series. I'm intrigued by this now, so I'd like to know.
