Brent's method

Hi,
do you still plan to implement a solve-method?
Like this, solve(cos(x^2)=0.5, x).
It would be great ;)

Kind Regards

Hello, I posted previous comment just to save the link to Brent's method algorithm (for future), but I'm not sure, when and how I will implement the Solve function (the current ticket was opened 4 years age =) ).

Probably, I should use external library (eg. Accord .NET), which has already implemented algorithm.

P.S. Also, these algorithms provide approximate solution, maybe there is a symbolic (like I will do it on paper, eg. same problem as for Integrals) algorithm.

Maybe we could integrate the Accord Algorithm. It sounds like a good solution, if the source is under the right license.

Do you mean Brents method is a good way to solve a function like x^2+y^2+z^2=4 for z?
Thx, Regards Ronny

The solve function is already implemented in my dev-branch. Please look into it, if you want to merge it into your code. I solved it with Newton-Raphson-Method.
