...well I feel stupid as all... lol thanks for clearing that up. ^^;

No, there's an axion in mathematics apparently where the variable "i squared" (i^2) equals -1. The reason I wrote a Capital I is because I'm working with a program called Maple. It's the same thing, but in the two matrices that I have to find, I can't use the -1 axion. Sorry for the confusion.

Homework Statement Find two different 2×2 matrices (other than ±I) such that A.AT = I. Definition: I is referring to i^2=-1 axion AT=Transpose of A Homework Equations The Attempt at a Solution Trying to make matrices on paper so that A times the transpose of A gives me -1 in...

k I think I got it... Given: u=[1,3,2] v=[-2,0,4] I put in the vector M(1)=[1,1,1] M:=<u|v|M(1)> and I get... [1,-2,1 3,0,1 2,4,1] I apply rref, and I get an identity matrix. Meaning that the above matrix is my answer, right?

Homework Statement Find a matrix whose kernel is spanned by the two vectors u=(1,3,2) and v=(-2,0,4). Homework Equations The Attempt at a Solution Tried setting vectors as a matrix and rref'ing it, but didn't know where I was getting at, also tried using an augmented identity...
