Evaluate lim(xto0) (e^(x)-e^(xcosx))/(x+...

Evaluate `lim_(xto0) (e^(x)-e^(xcosx))/(x+sinx).`

Text Solution

Verified by Experts

`underset(xto0)lim(e^(x)-e^(xcosx))/(x+sinx)=underset(xto0)lime^(x)(e^(x-cosx)-1)/(x+sinx)`
`=e^(0)underset(xto0)lim(e^(x-cosx)-1)/(x-xcosx).underset(xto0)lim(x-xcosx)/(x+sinx)`
`=1xx1xxunderset(xto0)lim(1-cosx)/(1+(sinx)/(x))`
=`(1-1)/(1+1)`
=0
