I can't translate a formula from Mathcad to Python. Stuck on the Find and rkfixed functions. Don't even know how functions Find and rkfixed works. If I would know I don't ask how to translate them. Of course you can tell me universal solution which tells how Find and rkfixed functions works not even for python. I would happy for any kind of your help.
T1, T2 are the initial approximations.
The first formula with Find()
T is the initial approximation.
The second formula with rkfixed()
