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...
