Let $\left(\Omega, \mathcal{F}, P\right)$ a probability space, and $X$ be an $N\left(0, \sigma^2\right)$-distributed real-valued random variable. For any $\theta \in \mathbb{R}$, compute (a) $E\left(e^{\theta X}\right)$ (b) Prove that $E\left(e^{\theta X^2}\right) = \begin{cases} \frac{1}{\sqrt{1 - 2\theta\sigma^2}} & \text{if } \theta\sigma^2 < \frac{1}{2} \\ +\infty & \text{if } \theta\sigma^2 \ge \frac{1}{2} \end{cases}$

Let $\sum_{n=0}^{\infty} a_n z^n$ be a power series whose radius $R$ of convergence is positive. Define $f: D_R(0) \to \mathbb{C}$ by $f(z) = \sum_{n=0}^{\infty} a_n z^n$. Let $S_N = \sum_{n=0}^{N} a_n z^n$ be the $N$-th partial sum. Show that $f(z) = \sum_{n=0}^{\infty} a_n z^n$ converges uniformly on every compact subset $A$ of $D_R(0)$, i.e. for every $\epsilon > 0$ there is an $N_0 \in \mathbb{N}$ such that for all $N > N_0$ and for all $z \in A$, we have $|f(z) - S_N(z)| < \epsilon$.
