ah right, not only fancy icons, but also some text
with that implementation you'll still have that problem with the moving target, that problem that i fixed last week in my algorithm. therefore I wrote ( x' -v0 ) in the DEq above
that
k^2 = 4 d m is right for both differential equations, since the oscillating part is part of the solution of the homogeneous equation.
but with that equations there in your png file, it's still "accelerated", like in my implementation, I still don't see a difference. anyway, it's a good idea to think about such stuff from scratch ( from scratch is somehow often a good idea
), currently I dont understand that exp log stuff myself.
