The blue grid doesn't show
up when printed or on overhead projection.
You can make the grid darker by
graphing sin(a*x)*sin(a*y)=0. Set a so that the
solutions are the grid lines. In the default zoom,
use a=2*pi. Darker2DGridLines.gcf demonstrates.
How can I label the x-axis in
units of pi?
You can label the x-axis by
pasting pictures next to it. AxisInUnitsOfPi.gcf uses this feature to add labels at units
of pi.
Graphing Calculator/NuCalc for Windows crashes when
I launch it.
The problem may be corrupt data
in the registry. Try deleting the registry entries
for NuCalc.
- Run Regedit
- Search for all entries
called "Pacific Tech", and delete each
one.
