 Jun8 accepted Complexity class notation Jun8 comment Complexity class notation Okay, I see! The thing that bothered me most was the multiplication between sets and elements of the sets - but this is obviously well-defined so should be no problem. Thanks!

Looking for “bad math” that “gets away with it” I wonder what kind of numerical system we could build out of this... Nov22 awarded Autobiographer May13 comment correct rotation and translation matrices Okay, I've been trying to fix my program, recalculating and recalculating.. Always coming to this result. Something seems wrong though, my program keeps given faulty results.. Apr28 comment correct rotation and translation matrices Yes, the determinant is $+1$ now. Apr28 comment correct rotation and translation matrices updated, with a more correct $M$... still not working though. Apr28 revised correct rotation and translation matrices added 140 characters in body Apr28 comment correct rotation and translation matrices I tried two different methods so far: 1. multiply rotation matrices $R_x$, $R_y$ and $R_z$ and 2. put the components of the $a^\prime_i$, calculated in $a_i$ in a matrix. 3. mess around with a graphical program, I think that's were I got this. Was kind of busy so might have messed things up. Apr28 comment correct rotation and translation matrices Hm yes your right.. Wow this really isn't my domain. Apr28 revised correct rotation and translation matrices Updated the matrix to one that has better results Apr28 comment correct rotation and translation matrices Ok I know for sure the matrix $M$ is wrong! Also for inverse transformations one should take the inverse and not the transposed as I have done. Some help on the correct transformation matrix would be great. Also, should I first rotate or first shift?
