*minimum angle*to

*minimum angle+angle range*)

It can be run in two different modes:

1. (equation for real pendulum)

2. (equation for small angle approximation :assume )

The damping factor b=0 is the default.

You can change it and find out what will happened.

For the second mode: the period and damping rate are the same for all pendulums. Do you know why?
