Question

Verify that the given function (explicit or implicit) is a solution of the corresponding differential equation:

y = cos x + C : y′ + sin x = 0

Sum

Solution

y = cos x + C

`dy/dx` = - sin x

⇒ y’ + sin x = 0

As a result, the function y = cos x + C provides a solution to the above differential equation.
