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

Re: Modified Euler method
Yes, we have done that but there is the little matter of determining the constant of integration.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Modified Euler method
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.
