Homework Statement We previously solved the heat conduction problem in a ring of radius a, and the solution is c into the sum, perform the sum first (which is just a geometric series), and obtain the general solution, which should only involve one integral in ϑHomework Equations...

So this is the work I've done and attempt to solve the last part. Could you take a look and see if there are mistakes? Thanks a lot. https://scontent.fsnc1-1.fna.fbcdn.net/hphotos-xlf1/v/t34.0-12/12966620_10153752402479331_217279662_n.jpg?oh=9654213d445a9df020ce5fbf28c18fad&oe=5715E168

Could you elaborate a bit on how this is supposed to rearrange the complex series to cosine series? Sorry, just really lost haha

So I casually stumbled upon this problem and tried solving the problem on my own just for fun, but doesn't quite get the answer to part B and C. For B, do you just ignored the sine portion of the Euler's identity since f(x) is an even function?
