Hello everyone!
I found a document in here containing a spreadsheet for calculating the motion of a triple pendulum and was quite excited to finally find an example of the physics behind this dynamical system. (Thank you rosenm!)
I'm a college student who have yet to learn about differential equations, so I'm not quite able to understand the math behind this system. So for simplicity I decided to try and "remove" the third pendulum from the system so I would end up with a double pendulum.
As it turns out, I wasn't so succesful in doing this! 
So my question is if anyone would be kind enough to "remove" the third pendulum from this document so that I could study it without getting a major headache?
Thanks in advance!
(I know that simply removing the third pendulum won't simplify it enough for me to understand it, but I still find it very exciting to study it!)
