\section{Added problems about the binomial theorem:} (a) Let $f(x) = 1+x+x^2/2 + x^3/6.$ Compute $f(x+1)$ using the binomial theorem.

\noindent (b, extra credit) Compute $e^{x+y}$ using $e^x = \sum_{n=0}^\infty \frac{1}{n!} x^n$ and the formula for binomial coefficients $\binom{n}{k} = \frac{n!}{k!(n-k)!}.$
