(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There is a sawtooth function with u(t)=t-π.

Find the Fourier Series expansion in the form of

a_{0}+ ∑α_{k}cos(kt) + β_{k}sin(kt)

2. Relevant equations

a_{0}= ...

α_{k}= ...

β_{k}= ...

3. The attempt at a solution

After solving for a_{0}, a_{k}, and b_{k}, I found that a_{0}=0, a_{k}=0, and b_{k}=-2/k

Therefore, my fourier expansion was the summation from k=1 to infinity of -2*sin(kt)/k

I think this is right, but can someone cross-reference final solutions with me? If you need to see my work I can provide that also.
