Project Description

I have a system of 3 simulatenous differential equations (equations 1,2 and 3) that I need to solve in ur(r), ut(r) and phi(r). These are engineering equations so the solution has to make sense.

These equations are simplified using physics to two equations (equations 4 and 5) in ur(r) and phi(r)

Project tasks:

Verify my derivation for the equations

Solving the differential equations (equations 1,2 and 3) closed form if possible if not in iterative

Solving the differential equations (equations 4 and 5) simulatenously...I think they can be solved in closed form solution since I can find solution to each but not simultaneously...
