प्रश्न

In the following verify that the given functions (explicit or implicit) is a solution of the corresponding differential equation:-

y = cos x + C            y' + sin x = 0

बेरीज

उत्तर

We have,
y' + sin x = 0 .....(1)
Now,
y = cos x + C
⇒ y' = −sin x
Putting the above value in (1), we get
LHS = −sin x + sin x = 0 = RHS
Thus, y = cos x + C is the solution of the given differential equation.
