- solved the a''=a^3 eqn in mathematica and attempted to plot a real version
- made a small script to plot a jacobi elliptic function that's similar to a=|1/n|
- included a function in ode3.py to calculate the scale factor if it were jacobi elliptic but realised cant use deriv as a''/a is not 1/n^2 as no longer a power law so the whole thing needs to be changed or different rules and functions when choosing to analyse different functions, a's etc
