1 -1 0 -1 1 2 0 8 4 4 2 0 v1= {1, -1, 0} and so on. Is it linear dependent? I think it is, since I read somewhere that if the Vector have less dimensions than it have vectors in the set then it's linear dependent. Or is it? I'm a bit confused.

Great, thanks a lot. Linearly independent vectors? I've seen that before when I looked for the answer, but I didn't quite understand it. How do I check if it's linearly independent?

Matrix: Ã= 1 -2 0 0 3 2 -5 -3 -2 6 0 5 15 10 0 2 6 18 8 6 Matrix on reduced echelon form: 1 0 0 -2 3 0 1 0 -1 0 0 0 1 1 0 0 0 0 0 0 X 0 0 -2 3 0 X 0 -1 0 0 0 X 1 0 0 0 0 0 0 Are the pivot positions the ones I've marked with X? And therefor colum 1, 2 and 3 are pivot columns...

Bump. Please, anyone. I really need this to get my paper approved, and I don't know where else to ask. REALLY would be appreciated. If you only can be bothered to solve one that is perfectly fine.

Anyone bored enough to want to help me out with some calculus? I got to deliver this in 6 hours and can't work these out. Help would be SO much appreciated, I've been at it all night and can't make it out. 1. y^2 - e^sin(x) + xy = sin (x)* cos (y) +3 assume y= y(x) and find y ' (0) 2...
