Does anyone know of a website to find trig functions (i.e. equations of
geometric objects, equation of the intersection of a line & a plane,
equation of line tangent to a circle.. you get the idea).  I need a
refresher for macros, etc.
Thanks.

There is a guy named Paul Bourke who has a homepage with lots of different
math and other stuff. It's gr8.
Check it out:

Look especially under Geometry.

Adding to that John Dlugosz has a couple of great math resource
links on his links page. His page is indexed and easy to navigate.

The Geometry Junkyard is my top pick.
