1. ## differential equation

kindly solve the attachments

2. ## Re: differential equation

Have you tried anything yourself?

3. ## Re: differential equation

Both of these only require that you verify that a given function satisfies a given equation. That requires only that you differentiate the given function and put those into the given equation. You do know how to differentiate? (You will need to use the fact that $\frac{d}{dx}\int_0^x f(t)dt= f(x)$. That is the "Fundamental Theorem of Calculus".)
