when you're multiplying two matrices together does it affect the answer at all if you swap the columns around in one of the matrices?

Does anyone have any ideas on how to construct an electromagnetically actuated micro pump? If so, please post.

G'day guys, got this question out of Step-by-step calculs by J.G. graham for those of you who have the book. I've had quite a bit of a play around with it but it doesn't seem to be going anywhere i end up with a few equations which have 3 variables, and i can't reduce it to two. Okay...

i would also be interested in the abstract algebra and integral calculus notes. please private message me also so we can arrange a way for me to receive the files.

I'm having trouble finding any good books and sites from which i can learn abstract algebra. Does anyone have any good suggestions so that i can learn the course? please include prices if possible

hey, if anyone is good with organic chem, could they please list some common and effective tests to distinguish between different organic compounds such as alkanols, acids and alkenes, etc.

Just a simple question, if u have an electric circuit that has a DC power supply, and you set it to 8 volts, u have an ammeter, lightbulb and variable resistor also in the circuit, does the current in the circuit change as the resistance changes, or is the current always constant?

Has anybody gone anywhere useful with it?

Hi, I'm having a few troubles with this question on my assignment. I've tried for many hours to get out the answer but i keep getting stuck and am not sure if I'm going about it the right way. This is the question: Three concurrent lines OA, OB and OC are produced to D, E and F...

does anyone know how teachers just make up questions for tests? is there any way of predicting the kinds of questions they will ask?

Just wondering if there's any guys in here that have past exams that they took in college or uni for vectors, stats and probability, complex numbers, calculus, etc. If you do it would be really great if you could scan them or something and send them to me so that i can prepare myself for the...

what are some of the types of questions you would put in tests that would most likely give them a bit of a hard time? we've just learned the product, quotient and chain rule and have done maximum and minimum problems, integration and differentiation aswell. not very advanced stuff on it though...

well i asked the teacher and he said that around 60% of the test will be just the standard questions which we have done in class, whereas the other 40% would most likely be the proofs and tougher questions which involve quite a lot of knowledge in the subject area. He said these questions would...

thanks for that guys. I do have a few past exam papers on the subject I'm learning at the moment and they all seem pretty easy, which is what I'm a bit worried about, because i know the one I'm going to have is going to be a lot harder. I think this because it happened to me in physics, i had...
