I usually like to use trig functions in degrees rather than radians-- just
easier to visualize for me. "math.inc" has some simple little 'converter'
functions, sind() and cosd()
So in your diagram, for example...
T5: y'= <0,cosd(180), sind(180>
But for your matrix illustrations, I don't know if they should be used (since I
don't know enough about matrix math).
like, -sind instead of -sin ??
