Question
Differentiate the functions with respect to x.
$\cos(\sqrt{\text{x})}$
✓

Answer

$\text{Let y} =\cos(\sqrt{\text{x})}$
$\therefore \frac{\text{dy}}{\text{dx}}= -\sin\sqrt{\text{x}}\frac{\text{d}}{\text{dx}}\sqrt{\text{x}} = -\sin\sqrt{\text{x}}.\frac{1}{2}(\text{x})^{\frac{-1}{2}}=\frac{-\sin\sqrt{\text{x}}}{2\sqrt{\text{x}}}$
