bobbym, Is it not possible for him to reduce this into a first order ODE by integrating both sides

Yes, we have done that but there is the little matter of determining the constant of integration.

there is but as far as I know when you are differentiating, you are loosing the information about the constants. Euler's method can give it back?

You can not get Euler's method going without a knowledge of the initial conditions.
