Question

Find the first derivative And second derivative of given function with respect to corresponding independent variable :
y= sin x + cos x​

Answer 1

Answer:

Step-by-step explanation:

y=sinx +cosx

$\frac{dy}{dx}$=$\frac{d}{dx} sinx+\frac{d}{dx}cosx$

$\frac{dy}{dx}$=cosx-sinx

$\frac{d^{2 }y }{dx^{2} }= \frac{d}{dx}cosx-\frac{d}{dx}sinx$

      =   -sinx-cosx
