This program makes easier the evaluation of the first
and second partial derivatives of w=f(x,y,z) with
respect to either x,y, or z.

You are asked to input w, a function of up to three
variables (x,y,z).  You are then prompted for the
x,y, and z values of the point at which the partials
will be evaluated.  Then you are asked to choose the
variable in which the partial will be evaluated with
respect to.  Output is gives the value of w at (x,y,z),
the fractional partial of w wrt {x,y, or z}, and the
fractional second partial of w wrt {x,y, or z}.
