I am working on oscillation and have been looking at the lotka-volterra equations. I may have misunderstood the question, but this is the equations:

y'= Ax-Bxy

y'=-Cy+Dxy

Can read quick about it here:http://mathworld.wolfram.com/images/equations/Lotka-VolterraEquations/Inline11.gif

I may have misunderstood, but i am supposed to find a numerical solution using Eulers method. Well, give an example of it. Can anyone help me pls. Really desperate.
