CAS ggb5/ggb6 different calculation results
An example session on attached applet
subject: constructing rotation matrix with vector axes
check matrix constuction to matrix formula of wickipedia (line 3)
Todo: Algebra - change rotation angle e.g w = 2 pi/3
I have to recalc the app (the image vectors line 6,8,11) multiple times until the constructed matrix will match wicki matrix. Problems on the way: CAS lines will be overwritten (undo back to correct state), Definition of image vectors ex',ey',ez' will be lost and replaced by other names. Recalculation of an image vector will change other image vectors, but recalculation of a image vector should have no effect to other image vectors.
If I use numeric arguments to w (w=2.25) the app seems to get stable results?
