| Topic | Am I the only one who finds linear algebra harder than integral calculus? |

Honestly this is the reason why I bombed my QM courses way back when. It was just calculus and some linear algebra. But the thing is the homeworks were tedious, so I got fed up doing my homework every single week (I have better things to do than to solve integrals with a billion and 2 variables for pages upon pages, like other homework and sleep), so I gave up halfway through not realizing that the actual theory that makes the HW worth it comes at the very end of the problems. When exam time comes out, that's when I learned the subject. And deeply regretted not finishing my HW problems. MacadamianNut3 posted... feel ya Sad Face. I knew how to calculate determinants no problem for years, but I didn't actually know that it just described how much an area is scaled after applying the matrix transformation until 4 months ago Really? Okay, that makes sense. I can see it now if you look at the Magnetic Force's equation, qv X B, (charge, velocity of a particle, Magnetic Field strength) and you can take the determinant to get the magnitude of the Force, or area of the 2 vectors. --- imgtc.com/i/4HgTl0ebzq.jpg imgtc.com/i/60CWP2Gtlg.gif ...
