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.

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?

Re: Modified Euler method

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