i got a complex numbers! [...] .the question is why!?
- You're taking the root of a negative number ,
- Or you're calculating the arcsin or arccos of a number outside [-1 1],
- Or you're doing any other mathematical operation that can result in complex numbers
Reread the formulae that you wrote. In particular, note that x^.2 is . Perhaps you meant x.^2
