I tried making one of these in AXE... so. slow. by. comparison.
Good Work Xeda! 1475

Maybe there should be a one byte option and a one sprite option.

How about the ability to update one pixel instead of the whole screen? (Ex. To make a fast Langton's Ant program)

I know that is wrong though because when I plug numbers back in, I don't get the right result

But shouldn't there be something done to the X in the exponent?

They're constants... I should have called them c and k, but the way I used is the way the problem is stated

abs(V(x))^2 is the same as V(x)^2

V(x) is squared... Did I not put that in?

Math and Science / Calculus with Velocities and other stuff« on: January 20, 2013, 03:58:59 pm »
So I have a system of equations:
Variables: V(x) - x velocity V(y) - y velocity C(x) - x constant C(y) - y constant t - time g - gravity constant dx, dy, dt, dV(x), dV(y), etc. - you can guess what these are Problem: dV(x) = C(x)*V(x)^(2)*dt dV(y) = (C(y)*V(x)^(2)+g)*dt dt = dy/V(y) = dx/V(x) solve for V(x) and V(y) in terms of x and y What I've done so far: dV(x) = C(x)*(dx^2/dt dV(x) = C(x)*V(x)*dx Vx^(-1)*dV(x) = C(x)*dx Integrate both sides (c is assumed to be 0 here) to get ln(abs(V(x))) = x*C(x) e^(x*C(x)) = abs(V(x)) good so far, right? I sub in e^(x*C(x)) for V(x) in the next equation dV(y) = (C(y)*e^(2*x*C(x))+g)*dt dV(y) = (C(y)*e^(2*x*C(x))+g)*(dy/V(y)) V(y)*dV(y) = (C(y)*e^(2*x*C(x))+g)*dy Now I'm stuck because I don't know how to integrate this equation Help, please! 1485
