| You're right! Now I understand why it doesn't work. y = Sqrt[1-e^2] z = Sqrt[1-f^2] In addition e, f are elements of (-1,1). Now it should work, I've forgot that I made all formulas for this assumptions (and I didn't know how... |
| I want to solve this: Solve[{-k - I Sqrt[1 - k^2] == (1 - (2 (e + I Sqrt[1 - e^2]) (f + I Sqrt[1 - f^2]))/(e + I Sqrt[1 - e^2] + f + I Sqrt[1 - f^2]))/(1 - (2 (e - I Sqrt[1 - e^2]) (f - ... |
