Derivative Rule:
Let y = ef(x) then
\(\rm \dfrac {dy}{dx} = e^{f(x)} \dfrac {d}{dx} f(x)\)
Calculations:
Given, f(x) = esin x
Taking derivative w. r. to x on both side, we get
⇒f'(x) = \(\rm \dfrac {d}{dx}\)(esin x)
⇒f'(x) = esin x \(\rm \dfrac {d}{dx} (\sin x)\)
⇒f'(x) = esin x \(\rm ( \cos x)\)
⇒f'(x) = \(\rm (\cos x)\)esin x
