Question

Find the derivatives of $\sqrt{x}$ + cosx

Answer 1

Step-by-step explanation:

$\sqrt{x} \frac{dy}{dx} + cosx \frac{dy}{dx} \\ {x}^{ \frac{1}{2} } \frac{dy}{dx} + cosx \frac{dy}{dx} \\ \frac{1}{2} ( {x}^{ \frac{1}{2} - 1} ) - sinx \\ \frac{ {x}^{ - \frac{1}{2} } }{2} - sinx \\ \frac{1}{ \sqrt{x} } - sinx$
