Function: inequalities - plot regions defined by inequalities
Calling Sequence:
inequalities( ineqs, xvar = a .. b, yvar = c .. d, options )
Parameters:
ineqs
- one inequality or equation or a set of inequalities and equations
xvar
- name for the x axis variable
a, b - bounds for xvar (real constants)
yvar - name for the y axis variable
c, d - bounds for yvar (real constants)
options - (optional) see below
