Homework Statement
Given the matrix A= 1 2, make a rule for A^n
0 3
Homework Equations
A^2= 1 8 , so the first and last numbers are put to the power given (i tried other powers)
0 9
But then what about the 8?
Another one: A^5= 1 242
0 243
I need to get a general formula... it seems as though the 242 is the last number-1
But then if I have something like B= -1 1
-16 7
It goes all strange
B^2= -15 6
-96 33
Ok, if I make it C= a b
c d
Is this right for C^2: a^2+c ?
? d^2+c
By the way, the ? mean I don't know
