Hi guys i just wrote a little programme to build a quarter of the under half of a sphere. If i run it i get about 9 times a "nan" and then it goes on…but this part doesn't matter.
I think something with the goSide function is wrong, because if i use it and then print the result i get "nan". But i really don't know how to solve it, maybe you got a tip with x^0.5?
I hope you can help me. Here the programm:
