2017-02-28 20:39:44 +0200 | commented answer | System of differential equations Thank you! But x and y are not variables, these are the i and j components of my pursuit curve, and they are functions of t. The graph should look a little bit like the one here: http://mathworld.wolfram.com/PursuitCurve.html (http://mathworld.wolfram.com/PursuitC...) (I'm sorry if you actually have x and y as functions, I am really new to sage.) |
2017-02-28 14:33:38 +0200 | asked a question | System of differential equations Hi! I am doing a project on pursuit curves, and I am trying to plot the system: with x(t) and y(t) being my i and j components for the trajectory a an object. I wrote: It gives me a solution for my system, x(t) and y(t) (that I don't understand, since I hacen't seen Laplace), but I can't figure out how to plot the vector equation A(t) = *x(t)i + *y(t)j. I wanted to use parametric_plot(x(t),y(t),(t,0,20)) but it doesn't work. Could anyone help me? Thank you! |
