I'd search for Maxima's "export expression to C code" function; then
paste it into my program and see if it's any faster than the numerical
solver I implemented as a stop gap while waiting on finding a closed
form solution..
To be honest the numerical solver I have is accurate and fast enough
already. Though, I'm still curious to see if a closed form solution
exists and would be faster...
