I am an IB student and in grade 11 and I really need some suggestions for my extended essay on physics. I want to do something that is relevant to 'communications' or something to do with Electrical Engineering, because that is what i want to do when I go into University, so it will help a lot...
Let A =
[ -3 9 ]
[ -1 3 ]
Find two 2x2 matrices B and C, such that AB = AC BUT B does not equal C.
I am stumped, but I am trying inverses and such, with no luck :(
Any insight would be great!:wink:
Hello All-
Below is a picture of a cargo crawler I've been thinking of. Gross weight would be 2000lbs, moves between 1.5- 3mph, crawls on pavement or concrete. So far I've come up with aluminum tube welded frame with wheel motors at the rear, either motorcycle type or electric forklift type...

Hi,
I just wanted to know if there's any particular textbook on dynamics that you would suggest. I've been thinking of buying the one by Beer et al. or Riley & Sturges, because they are the ones suggested by our teachers. However we're not using them in class and I also saw other books by...

Hello,
I'm looking for a not-to-expensive webhosting company for relatively small sites. I'm currently with Lycos, but they are extremely lousy and expensive for the bad service you get. I heard 1on1 isn't too bad, but what are the experiences and are there other suggestions ?
thanks!
I am a senior in high school in the US currently looking for the right college(s) to apply to. I am looking to major in physics and I am currently thinking about going to graduate school afterwards to get a PhD in physics, although this may change.
