What is the best way to plot two curves with different Y axis scales?
Such as Sin[x] and 2 Sin[x^2]+Cos[x] for example.

One method is to rescale each individual curve (so that in the we would
then have
Sin[x] and  2/3 Sin[x^2]+Cos[x]/3 as a scaled function) and then write
out
the FrameTicks->{Automatic, {y1 ticks}, None, {y2 ticks}}, where
y1 and y2 are an array of ticks.   Is there a package that does that
does something similar for Mathematica version 4.0?
