sympy: system of equations for double pendulum

Asked 2019-Aug-15 at 17:29

I want to solve system of equation described in the article Double Pendulum, similar like author, where in last step he claims that he "use a computer algebra program to solve equations (13) and (16)". To do this, I rewrite this equations in SymPy:

This sort of manipulation is described here; using the focus routine described there you can feed your full equation set (cast as Eq instances) to focus and specify y1_d2 and y2_d2 as the variables on which you want to focus:

QUESTION

Odd slowing effect on a double-pendulum animation with python tkinter

Asked 2018-Aug-07 at 10:21

I am just getting started with python and tried to create a double-pendulum animation using tkinter. I am aware that because of my inexperience, I likely took a convoluted approach.

I have an error that I did not expect. It seems that the pendulum slows down oddly in places. In time, the energy of the system seems to go down, which should not happen, as I have not accounted for any friction.

I do not think I made an error in my formulae for theta1_dotdot and theta2_dotdot, because the slowing happens even when I use simpler (non-physical) formulae.

Here is my program:

I've rewritten your code to remove blanket imports (import *), use a class structure rather than globals and functions, and to actually use the tkinter mainloop and after function properly:
