 6 Show that $\sum \frac{z^n}{n}$ diverges if $z = 1$ but otherwise converges if $|z|=1$. 5 fundamental theorem of calculus relation 5 Proving that the dual of the $\mathcal{l}_p$ norm is the $\mathcal{l}_q$ norm. 4 radius of convergence for $\sum_{n=1}^{\infty} \frac{z^{n} n^{n}}{n!}$ and $\sum_{n=1}^{\infty} z^{n!}$ 4 where does $\frac{1}{1-z}$ about the point $5i$ converge.

 +5 how to project optimal parameters on to feasible region +5 why not handle box-constraints with a transformation +10 First-Order Linear Difference Equation with Constraint +5 why does this simple function converge to f(x) pointwise

 0 finite geometric series has a known sum. does this imply anything about the halfway point ? 0 not following two steps in proof that $\int_{0}^{\infty}\cos(x^2) = \frac{\sqrt{2 \pi}}{4}$
