HI everyone, im currently using maple 15 and im trying to animate at least the mass of my pendulum. My problem is that the  coordinate of each mass would be the solution of two numerical ODE and I can't animate this. I am able to plot the solution of my ODE (wich correpond to the two angle in the pendulum), but when it comes to animating... its an another piece of work. So here is what I tried: the code would correspond to the animation two masses... no rope yet.

Hi everyone, im trying to solve the following system of ode (motion of a double pendulum) where im trying to plot numerical solution for T1(t) and T2(t). Been searching for a while... found nothing :) Here is my code , i also loaded the library plots, DEtools. . Im using maple 15

> Systeme := [2*(diff(T1(t), x, x))+cos(T1(t)-T2(t))*(diff(T2(t), x, x))+sin(T1(t)-T2(t))*(diff(T2(t), x))^2+19.6*sin(T1(t)) = 0, diff(T2(t), x, x...

Hi,

Im trying to animate a simple pendulum with maple 15. I'm able to make to the pendulum masse move, but, somehow, I can't animate the rope of the pendulum. I tried to draw the rope with the plottools library line , but no success.

Pendulum:=proc(x,y)plots[pointplot]([x,y],color=blue, symbol=solidcircle,symbolsize=25) end proc:
A:=animate(Pendulum,[XCoordinate,YCoordinate],t=0..8,frame=100):
Rope:=plottools[line]([0,1],[XCoordinate,YCoordinate],color=blue,thickness=3):
