Hola!
I was using Mathematica to visualise trajectories of x[p],y[p] depending on p.
Is it possible?
Talking about "it's simple
to animate the parametric plot of them by using ParametricPlot inside
Animate."
But I cannot animate the NDSolve using ParametricPlot.
Can you please tell me why I get errors like "NDSolve::dsvar: 1.0011952113073699` cannot be used as a variable. ":
Animate[
ParametricPlot[
{Evaluate[{y[p], x[p]} /. sol =
NDSolve[...some equation type D[f1[x[p],y[p],p] = -D[x[p], p],
f2[x[p],y[p],p] = -D[y[p], p]
x[1] == -1, y[1] == -1}, {y[p], x[p]}, {p, 1, Tp}]]},
{p, 1, Tp}], {Tp, 1, 100}]
Thank you!
