Answer:

Verified

Hint:

Find the first and second derivative of given function and put in differential equation to verify

Given:

$y=\cos x+c$

${y}'+\sin x=0$

Solution:

$y=\cos x+c$

${y}'=\frac{dy}{dx}=-\sin x$

Put in differential equation,

${y}'+\sin x=0$

$-\sin x+\sin x=0$

$\Rightarrow 0$

Hence verified
