limits question........

OMG Kpop Fan?

OpenStudy (hyuna301):

\[\lim_{x \rightarrow 0} (e ^{^{tanx}} - e ^{x})/tanx - x\]

\[is~your ~question~like ~this?\lim_{x \rightarrow 0}\frac{ e ^{\tan x}-e^x }{ \tan x-x }\]

OpenStudy (hyuna301):

yupp...

OpenStudy (legomyego180):

You're going to need to use l'hopitals :)

OpenStudy (legomyego180):

tan (0) = 0 which means this is indeterminate

OpenStudy (hyuna301):

then u need to make it determinant form...........the given answer is 1 but i am unable to solve it

OpenStudy (sshayer):

\[\lim_{x \rightarrow 0}\frac{ e ^{\tan x}-1+1-e^x }{ \tan x-x }\] \[\lim_{x \rightarrow 0}\frac{ \frac{ e ^{\tan x}-1 }{ \tan x }\times \tan x }{ \tan x-x }-\lim_{x \rightarrow 0}\frac{ e^x-1 }{ \tan x-x }\] \[=\lim_{x \rightarrow 0}\frac{ \frac{ e ^{\tan x}-1 }{ \tan x } \times \frac{ \tan x }{ x } }{ \frac{ \tan x }{ x } -\frac{ x }{ x }}-\lim_{x \rightarrow 0}\frac{ \frac{ e^x-1 }{ x } } { \frac{ \tan x }{ x } -1}\]

OpenStudy (sshayer):

\[\lim_{x \rightarrow 0}\frac{ e ^{\tan x}-1 }{ \tan x }=1\]

OpenStudy (sshayer):

\[\lim_{x \rightarrow 0}\frac{ \tan x }{ x }=1\]

OpenStudy (sshayer):

\[\lim_{x \rightarrow 0}\frac{ e^x-1 }{ 1 }=1\]

OpenStudy (sshayer):

now you can complete it.

OpenStudy (hyuna301):

thanks a lot..

OpenStudy (legomyego180):

Wolfram agrees

OpenStudy (sshayer):

i think we have done wrong we have to use L hospital,s rule in between but sorry now i am going to bed.

OpenStudy (hyuna301):

ur answer is correct lol.........
