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
