| divinomas 26. Sep 2008 | Hi. I didn't get your real intention.Anyway,I have forgotten differential equation for a while.Mapple gave me the result -tanh(ln(x)+_C1) for your "diff(y(x), x) = (y(x)^2-1)/x" equation. PS:You are a school boy,do you?So many formulas ;) Regards |
| MR.HAANDI Author 26. Sep 2008 | Yes, to solve it you have to 1. Understand the basic VM. (shouldn't be challenging) 2. Get the function. (60% af the task) 3. Transform the function into VM code. (30%, here you have to use a few tricks) I just want ppl to use their braincells and maybe learn a little. And in five days I won't be a school boy anymore ;) |
