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 $\displaystyle -\pi$ and $\displaystyle \pi$ not $\displaystyle 0$ and $\displaystyle \pi$

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

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

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

What else have I done incorrect?

Regards.

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