Is e^-x = 1/e^x? - Quora

Yes, e^-x = 1/e^x Proof: Let P denote the product of e^-x and e^x Then P = e^-x . e^x = e^ (-x+x) = e^0,……………………………(1) since according to the. I'm finding the critical points of f(x) = e x - x. First step: Find f'(x) f'(x) = e x - 1 Second Step: Set to 0 and solve for x e x = 1 My question now is how to solve for x.. Find the differential dy when y=e^(x/10) And evaluate dy and the change of y if x=0 and dx=0.1 I have no idea where to begin, if someone could list the steps to this problem, and general steps to solving problems like this it would be much appreciated. Thank you for any help.
