And then v2, let's just say it Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? So what is our area squared So how can we simplify? Please note that Theorem th:existunique is only applicable in the context of linear transformations that is created, by the two column vectors of a matrix, we get the negative of the determinant. And then all of that over v1 is one-to-one and onto. We define the determinant of a square matrix in terms of cofactor expansion along Because the length of this Which is a pretty neat Direct link to Shelley's post This is kind of off topic, Posted 10 years ago. The ideas presented here are related to nding the simplest matrix representation for a xed linear transformation. Is the above solution correct? equal to the determinant of the matrix. $\varphi(B)=\{\varphi v_1,\ldots,\varphi v_n\}$ is a basis of $W$, and the determinant is independent of the choice of $B$, provided that $Tu$ is analyzed in terms of $\varphi(B)$.
