# Thread: Some queries on Fourier Series.

1. ## Some queries on Fourier Series.

Please see attached. I struggle with Latex so this was easier.

Any assistance much appreciated.

For 1. the limits are $-\pi$ and $\pi$ not $0$ and $\pi$

For 2., what is the integral of $3-2x$?

If by $a_0$ you mean the constant term then the multiplier if the integral is $1/(2\pi)$ if the constant term is $a_0/2$ then the multiplier is $1/\pi$ it all depends on how $a_0$ has been defined.

Integral of 3 - 2x = 3x - x^2...

What else have I done incorrect?

You consistently seem to try to evaluate the limits of integration as $0$ and $\pi$ rather than $-\pi$ and $\pi$
