(Assume we are talking about everything in Euclidean vector spaces up to an isomorphism and everything here is finite dimensional) Now think of a map $T: V\rightarrow W$ and $\dim{V}<\dim{W}$, the image of a unit cube in $V$ is then an $\dim{V}$-dimensional "sub-"parallelepiped in $W$ thus has volume $0$.

We have a minus cd squared As you recall, a matrix representation is determined once the bases for the two vector spaces are picked. You have that, $T$ is a linear transformation $\iff$ $T(u+v)= T(u)+T(v)$ and $T(\lambda u)=\lambda T(u)$. the length of that whole thing squared. So this is just equal to-- we equal to our area squared. This shows us that all such determinants are simply fixed multiples of each other, something which is not immediately obvious from the formulation in terms of bases. Verifying a Linear transformation from M 2,2 -> R, Describing the action of T (linear transformation) on a general matrix. linear, but it turns out that the requirement that S\circ T=\id _V and T\circ S=\id _W is sufficient to guarantee that S If you fix an isomorphism $\varphi\colon V\to W$, then you could take the determinant of $(T,\varphi)$ by picking a basis $\mathcal{B}$ for $V$ and taking the determinant of the matrix of $T$ with respect to $\mathcal{B}$ and $\varphi(\mathcal{B})$ as Yiorgos suggests - this doesn't depend on $\mathcal{B}$ for the same reason as in the $V\to V$ case, but it does depend on $\varphi$.
