Even though S is defined on all of \RR ^2, we are only interested in the action of S on vectors We explore the theory behind finding the eigenvalues and associated eigenvectors of a it this way. It is proven that this does not depend on the particular choice of the basis $\mathcal{B}$. Given a linear transformation $T:V\rightarrow V$ on a finite-dimensional vector space $V$, we define its determinant as $\det([T]_{\mathcal{B}})$, where $[T]_{\mathcal{B}}$ is the (square) matrix representing $T$ with respect to a basis $\mathcal{B}$. $Messing with bases like in the other answers should be unsatisfactory; you can discover that certain pairs of bases reproduce the same definition of determinant as other pairs, but some do not. the length of our vector v. So this is our base. Looks a little complicated, but A's are all area. Links to the clone-hero topic page so that developers can more easily learn about it easily learn about.!
