I checked Maple, MATLAB and Mathematica websites and found personal/home editions for hobby use like 3D printer, robotics, etc.. and self-study. I now have a few questions for you. Does anyone have any good experiences with them? Which software support step-by-step solution display like solving or simplifying algebra or calculus formulas each step? That would help refreshing. I was looking for MapleSim personal edition but Maplesoft website did not mention but just student or professional versions. Does MapleSoft offer MapleSim personal/home edition that MathWorks does? Thanks!
