Question

In each of the question verify that the given functions (explicit or implicit) is a solution of the corresponding differential equation: y = cos x + C : y′ + sin x = 0

Philoid · Accepted Answer

It is given that y = cosx + C

Now, differentiating both sides w.r.t. x, we get,

⇒ y’ = -sinx

Now, Substituting the values of y’ in the given differential equations, we get,

y’ + sinx = -sinx + sinx = 0 = RHS.

Therefore, the given function is the solution of the corresponding differential equation.
