Use induction to prove that, for $n \ge 1$: $\sum_{i=1}^{n} \frac{1}{2^i} = \frac{2^n - 1}{2^n}$ We recommend using "Preview My Answer" before clicking "Submit". Proof: We will prove this by induction on $n$. Basis: Let $n = $ . Then $\sum_{i=1}^{n} \frac{1}{2^i} = \sum_{i=1}^{1} \frac{1}{2^i} = \frac{a}{b} = \frac{c}{d} - \frac{e}{2} = \frac{2^n - 1}{2^n}$ a = , b = , c = , d = , e = Induction Hypothesis: Assume $\exists k$ such that $\forall n$ with $1 \le n \le k$, then $\sum_{i=1}^{n} \frac{1}{2^i} = \frac{2^n - 1}{2^n}$. f = Induction Step: Consider $\sum_{i=1}^{k+1} \frac{1}{2^i}$ Then $\sum_{i=1}^{k+1} \frac{1}{2^i} = \sum_{i=1}^{k} \frac{1}{2^i} + \frac{1}{2^{k+1}}$ g = , h = $= \frac{2^k - 1}{2^k} + \frac{1}{2^{k+1}}$ By the induction hypothesis j = , l = , m = $= \frac{2(2^k - 1)}{2^{k+1}} + \frac{1}{2^{k+1}}$ p = , q = , r = $= \frac{2^{k+1} - 1}{2^{k+1}}$ s = , t = Thus, by the property of mathematical induction, $\sum_{i=1}^{n} \frac{1}{2^i} = \frac{2^n - 1}{2^n}$ for $n \ge 1$. $\square$

Euler's equation can be written: $\frac{\partial \vec{v}}{\partial t} + \nabla \left(\frac{1}{2}v^2\right) - \vec{v} \times \left(\nabla \times \vec{v}\right) = \vec{f}_{ext} - \frac{1}{\rho}\nabla p$ (a) Show that from this equation you can obtain Bernoulli's Theorem: $\frac{1}{2}\rho v^2 + \rho V_{ext} + p = \text{constant}$ Clearly state all assumptions made.
