2020-21 Meeting 9: Fun Sums and Products

Who knew that sequences and series could be so cool?

Addition by itself is pretty boring. But when we start dealing with cool sums with clever closed forms, things start to get interesting. We talked about a clever combinatorial argument, linearity of expectation, roots of unity, and the Basel problem, all cool applications of sums and products.
