1 # a rope slides frictionlessly down the edge of a table

2 # x'' = g/l * x

4 coefficient(1): 1 -> x0' # initial speed

5 coefficient(2): -1 -> -x0 # initial length of rope already over the edge of the table

6 coefficient(3): g/l # gravity constant (g) divided by the length of the rope (l)

8 iintegrate (x'') -> -x':

9 IC: x0'

10 iintegrate (-x') -> x:

11 IC: -x0

12 x * g/l -> g/l*x = x''

14 # note: positive x-axis in the direction of the falling rope (so down)

15 # for visualization, -x is displayed

16 invert (x) -> -x # goes to output x
