The Mathematica commands Solve[], NSolve[], and FindRoot[] can all be used to
solve systems of nonlinear equations.  The breakdown is as follows:
Solve[] - attempts to find symbolic solutions
NSolve[] - Finds numerical solutions to polynomial equations
FindRoot[] - Finds numerical solutions to general equations
 
FindRoot[] uses a simple Newton's method, and may or may not work well in a
particular case.
 
The problem is that the normal convention for Mathematica was not used here.
Usually, the function beginning with N is a numerical version of the
symbolic function that does not begin with N.  This convention was not
followed in this case.
