oh my lord...quotient rule will send chills

helder_edwinBest ResponseYou've already chosen the best response.0
using L'Hôpital's rule \[ \large \lim_{x\to0}\frac{e^{\tan x}e^x}{\tan xx}= \lim_{x\to0}\frac{e^{\tan x}\sec^2xe^x}{\sec^2x1} \] \[ \large =\lim_{x\to0}\frac{e^{\tan x}\sec^4x+e^{\tan x}2\sec^2x\tan xe^x}{2\sec^2x\tan x} \]

L'H rule wont work here, use expansion

\[e^{\tan x}=1+\frac{\tan x}{1!} + \frac{\tan^2x}{2!}+\cdots\\e^{x}=1+\frac{x}{1!} + \frac{x^2}{2!}+\cdots\\e^{\tan x}e^x=\frac{\tan x  x}{1!}+\frac{\tan^x  x^2}{2!}+\cdots\]

each numerator has a factor \(\displaystyle \tan x  x\) \[\Large \frac{e^{\tan x}e^x}{\tan x  x}=\frac{(\tan x  x)(\frac{1}{1!}+\frac{\tan x + x}{2!}+\frac{\tan^x+x \tan x+x^2}{3!}+\cdots)}{\tan x  x}\]
