lim(xtooo) (e^(1//x^(2))-1)/(2tan^(-1)(x...

`lim_(xtooo) (e^(1//x^(2))-1)/(2tan^(-1)(x^(2))-pi)` is equal to

A

`e^((1-e))`

B

`e^(((1-e)/e))`

C

`e^(((e)/(1-e)))`

D

`e^((1+e)/(e))`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset(xtooo)lim(e^(1//x^(2))-1)/(2tan^(-1)(x^(2))-pi)=underset(t to0^(+))lim(e^(t^(2))-1)/(2cot^(-1)t^(2)-pi)`
`=underset(t to0^(+))lim(e^(t^(2))-1)/(-2tant^(2))`
`=underset(t to0^(+))lim-(1)/(2)(e^(t^(2))-1)/(t^(2)(tant^(2))/(t^(2)))=-(1)/(2)`
