Question

Please help If f(x)=sinx, then f′(π/3) =

Answer 1

`f' \left((\pi)/(3)\right) =(1)/(2)`

Explanation:

Given function:

`f(x)=\sin x`

The differentiation of sin(x) is cos(x).

`\implies f'(x)=\cos x`

Therefore:

`\implies f' \left((\pi)/(3)\right) = \cos \left((\pi)/(3)\right)`

`\implies f' \left((\pi)/(3)\right) =(1)/(2)`
