Hi,

     I'm trying to find the zero's of a 'nearly parabolic' trajectory, so narurally there are two zeros' of course I don't care about the first zero only the second one. Is there a way to have fsolve find both, or just skip the first?

     Restricting the range of fsolve won't work because I don't know where my first of second zero will be.  
Thanks!

Hi,

     I wish to plot the trajectory of a ball, and I set up my three differential equations and solved them numerically. I can graph the x, y, z components but I can’t figure out how to plot 3D space curve of this (and animate it if possible).

I used dsolve, numeric rtk45, so the output is [t, x, x’, y, y’, z, z’] so I tried to assign the second (and 4^rth and 6^h) term in the list to a function
