comment How to dynamically plot the trajectory of a particle from the ODE solution?
@GastonMaffei Don't expect "fully complaint" answers in these sites, but food for thought. Try to use the answers you get for building up your knowledge and as the basis for your own effort.

comment Multivariate resultant in Mathematica?
@DanielLichtblau The limit of three polys/vars seems hardcoded somewhere (strange). It doesn't matter if the input is symbolic or not: with more than three polys it spits out the input. Anyway, it's too easy to crash, so I think the version I've here is just barely debugged.
