Here's a calc 2 question that has been irritating me for a while: Use the maclaurin expansion for e^x to show that e = (reimannsumof) from 0 to infiniti of 1/n!.... what theorems about series are involved in justifying this claim?
Also, should I just memorize these maclaurin sums... ?

Best ResponseYou've already chosen the best response.0\[e^x=1+\frac{x}{1!}+\frac{x^2}{2!}+\frac{x^3}{3!}+\frac{x^4}{4!}+\frac{x^5}{5!}+...\frac{x^n}{n!}\]
