## Homework Statement

A given matrix [tex]

A(x) =\left | \begin{array}{cc} cos(x)&sin(x)\\ -sin(x)&cos(x) \end{array}\right |

[/tex]

Find the term in the first row and second column A^{5}(x) when x = 18°

## Homework Equations

## The Attempt at a Solution

Instead of multiplying the matrix again and again by itself in a iterative procedure is there any quicker way?

Thanks

Thomas
