I am an absolute beginner with Maple and am appreciating any help.
Basically, I want to use maple because it can deal with algebraic expressions. For example with Matrixmultiplication I don't just want to see the final result, but also I want to see the algebra behind each matrix element.
So I have defined the following 2 matrices :
rot_x := matrix([[1,0,0], [0, cos(alpha), -sin(alpha)], [sin(alpha), cos(alpha), 0]]);
rot_y := matrix([[cos(alpha), 0, sin(alpha)],[0,1,0],[-sin(alpha), 0, cos(alpha)]]);
