I am kind of stuck on this. How can I compute the cartesian coordinates of a euclidean point in PGA?
My guess is that I can reverse the representation of a point, e.g., for 2D PGA:
Euclidean Point at (x,y) := xe20 + ye01 + e12
So if I have some Point (x,y), would I substract
e12 and then the cartesian coordinates are the values of the
e20 and the
