Hi everbody, I'm a Physics Italian Student and I'm getting started to use Mathematica 5.1.
I should solve a very simple problem, i.e. the motion of a charged particle in an electro-magnetic field...the particle moves along the x axis, the electric field E is along the y axis and the magnetic one B is along the z axis, so the motion of the particle is determined by this system (I guess it's obvious, however x' and x'' indicate the first and second time derivative)
m x'' = qB y'
m y'' = -qE - qB x'
with the initial conditions
I managed to solve the system (I attached my script), but I don't know how to impose the initial conditions, so I got some strange syntax errors...could somebody please explain me right syntax to use?
I hope this is the righ place to make this answer...otherwise, my apologies (and sorry for the bad English!)!
