I simply cannot get interested in geometry, but i realize it's an adequate skill to have, does anyone have any tips for me? It's also not a matter of mathematical skill since I'm still in the 10th grade and am already capable of doing S.A.T level 5 problems, i just find them a nuisance to...

does anyone have any tips on learning how to do proofs. completing a proof isn't something I am good at, at all. I know how to get answers and I can do the math but explaining it to someone step by step, using the right communication. Seems like a foreign language to me. any tips on learning...

Hey everyone! I've gotten some really good help over in the math section of physicsforums, and I was hoping to get some more of the same here in engineering. I've just finished my sophomore year in school, and I'm about to apply for the EE program at the university in spring. Anyway, I...

I always get screwed over by labs/tutorials. The overhead that I have from physically moving from the University library to the lab room and back always demolishes my time. If I don't attend the labs, then I can study in one single slot of time. However, if I go to the labs, then I can't do...

Hey guys. I'm trying to gather some tips that people have acquired that helps them write the Lagrangian for a system. Obviously, the classic examples are drilled into our heads over and over, but just when you think you can tackle any problem the professor throws at you, there is that tricky one...

I have done some "proofs" before in calculus. At this moment I am required to write proofs for linear algebra and I find them highly unintuitive and confusing -- I often don't know where to begin or what to do. Can you guys leave some pointers, tips, advice, etc. for how to prove things...

Topic says it all really, thanks.
