`lim_(xrarroo) (e^(1/x^(2))-1)/(2tan^(1)(x^(2))-pi)=`

A

`-1/4`

B

`-1/2`

C

`1/2`

D

Does not exists

Text Solution

Verified by Experts

The correct Answer is:
B
`lim_(xrarroo) (e^(1/(x^(2)))-1)/(2tan^(-1)(x^(2))-pi)=lim_(xrarroo) (e^(1/(x^(2)))-1)/(2((pi)/2-cot^(-1)x^(2))-pi)`
`lim_(xraroo)=(e^(1/(x^(2)))-1)/(-2tan^(-1)1/(x^(2)))=-1/2`
