Hi! I'm developing a GUI tool and I would like to have help tips pop up whenever the mouse cursor points at a specific field.

solving nonlinear simultaneous equations
Hello. I'm trying to solve the following set of non-linear simultaneous equations for U and V: 1. U^3 + U*(V^2) = ((a*8*g*h)/f)^2 2. V^3 + V*(U^2) = ((b*8*g*h)/f)^2 Please note that a, b, h, U and V are matrices. Since this is a cubic equation, I may have a complex conjugate root and a real root. I want to... 19 May 2010 03:54
