Excel can solve equations through several of its mathematical functions, but the single Excel tool that works on the largest variety of equations is the program's Solver Add-in. This tool reads an ...

A procedure is introduced for solving systems of polynomial equations that need to be solved repetitively with varying coefficients. The procedure is based on the cheater's homotopy, a continuation ...

The stiffness in some systems of nonlinear differential equations is shown to be characterized by single stiff equations of the form $$y' = g'(x) + \lambda \{y - g(x ...
