The value of lim(xto0) (1+sinx-cosx+log(...

The value of `lim_(xto0) (1+sinx-cosx+log(1-x))/(x^(3))` is

A

1

B

-1

C

2

D

-2

Text Solution

Verified by Experts

The correct Answer is:
B
`underset(xto0)lim(1+sinx-cosx+log(1-x))/(x^(3))`
`=underset(xto0)lim(1+(x-(x^(3))/(3!)+...)-(1-(x^(2))/(2!)+(x^(4))/(4!)-...)+(-x-(x^(2))/(2)-(x^(3))/(3)-...))/(x^(3))`
`=-(1)/(3!)-(1)/(3)=-(1)/(2)`
