For each of the following initial value problems verify that the accompanying function is a solution:

Function: y = sin x + cos x

Answer :

y = sin x + cos x

Differentiating both sides we get,

Therefore, sin x + cos x is the solution of the differential equation.

Also at x=0, we get y=sin 0+ cos 0 which is equal to 0+1=1.
