\lim \limits_{{x \rightarrow 0}} \frac{a \sin x-b x+c x^2+x^3}{2 x^2 \log (1+x)-2 x^3+x^4}

exists and finite, then which of the following is not correct?

View answer and explanation

Correct option: A

a=6

Option A (

a=6

) is correct because the limit exists and is finite only if

a=6

b=6

, and

c=0

. Therefore,

a=6

is the correct value.
