There is no closed-form mathematical solution to the problem.

A solution was found using a power series but you would need to use 10^8000000 terms.

Numerical techniques can be used but those are approximations. Those approximations lead errors calculating initial conditions for the next iteration leading to widely divergent solutions.

Kevin, you may want to jump in here.
