A function f is defined by `f(x)=e^(x) sin x` in `[0,pi]`. Which of the following is not correct?

A

f is continuous in `[0, pi]`

B

f is defferebtiable in `(0,pi)`

C

`f(0)=f(pi)`

D

Rolle's theorme is not applicable to f x on `[0,pi]`

Text Solution

Verified by Experts

The correct Answer is:
D

Clearly, f(x) is continuous on `[ pi,pi]` and differentiable on `(0,pi)` such that `f(0)=f(pi)=0`
So, Rolle's theorem is applicable to f(x) on `[0,pi]`.
Hence, option d is not correct
