Question

Find the derivative of f(x) = sin x, at x = π​

Answer 1

Answer:

-1 is derivative of f(x) at x = π

Step-by-step explanation:

f(x) = sin x

f'(x) = cos x

f'(π) = cos (π)

      = -1

Answer 2

Concept

Recall formula will use to solve

$\frac{d \sin x}{dx} =\cos x$

Given

The function f(x) = sin x.

Find

We have to find the derivative of the given function at x = π​.

Solution

Given f(x) = sin x

then f'(x) = cos x

At x = π​

f'(π) = cos (π)

      = -1

Hence the derivative value at x = π​ is -1.
