Math Is Fun Forum

I am doing an IA on matrix powers. I want to know a formula for S^2= (4 2
          2 4 and the general pattern.
I dont know what they mean by generalize these results in terms of k and n for a matrix that looks like this.. (k+1 k-1
                                                            k-1 k+1) or
Use technology to investigate what happens with further values of k and n. State the scope or limitations of k and n.
