I caught a few small errors in Homework 5.
- In Problem 1, the Maclaurin series for sine and cosine were slightly off.
- In Problem 5a, the formula for the Fourier series should have involved a sum over only odd integers.
Both errors have been corrected and the new version has been uploaded. (You may need to refresh your browser before clicking the download link below.)
I have also uploaded solutions for this homework. Hopefully they can be some help if you get stuck (or would like to check your work)!
