Re: [Algorithms] Euler's integration

[Erin C. <eri...@ya...>]

If the acceleration is constant, there is no need to
perform time stepping. If the acceleration is not
constant, you can do much better than Euler's formula
or Newton's formula.

I suggest the 4th order Runge-Kutta to get started.
See "Numerical Recipes in C++."
