 Author Comment/Response Carlo 10/21/08 12:14pm 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 x(t=0)=0 x'(t=0)=Vo y(t=0)=Yo y'(t=0)=0 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!)! Attachment: campo_tot2.nb, URL: ,
