Question

If $b = a - \frac{a^{2}}{2} + \frac{a^{3}}{3} - \frac{a^{4}}{4} + ..$ then $b + \frac{b^{2}}{2!} + \frac{b^{3}}{3!} + \frac{b^{4}}{4!} + ...\infty =$

Answer 1

Given $2e$

$3e$ ⇒ $4e$

Question: If \(b = a - \frac{a^{2}}{2} + \frac{a^{3}}{3} - \frac{a^{4}}{4} + ..\)then \(b + \frac{b^{2}}{2!} +...
