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 ??
