Sorry for the format, I'm on my phone. Lets say the matrix is | 1 1 1 | | a b c | | a^2 b^2 c^| Or {{1,1,1} , {a, b,c} , {a^2, b^2,c^2}} Show that it equals to (b-c)(c-a)(a-b) I did the determinant and my answer was (bc^2) - (ba^2) - (ac^2) + (ab^2) + (ca^2) - (cb^2)...

Ohhhh I see it now! Thank you guys. The professor just rushed through this part and didn't really give us time to ask questions about it. I appreciate it!

In our Linear Algebra class we barely touched on (and I mean barely touched up on) circuits. Thing is, it will be on the exam, but just 1 question. My problem is understanding how to get the formula to use Cramer's Rule Of course I know how to set these up into Matrices and do all of...

OH It was because of the third problem sin(3n)/n^2 Is it because sin(3n) / (n^2) ≤ 1/(n^2) Therefore the p test makes it absolutely convergent? I had the other 4 right, I figured that one was A though, is this the reason?

I have some problems here with Series and Convergence... Here are the problems and my guesses at it. http://img822.imageshack.us/img822/9523/23341530.png It won't tell me which one is wrong, but it just says one/all is wrong. Any help is appreciated. Attempts at solving, I tried...
