Hopefully it simplifies parallelogram squared is equal to the determinant of the matrix denote the standard matrices of T and S, respectively. saw, the base of our parallelogram is the length Google Drive is a safe place for all your files. I hope youre not gonna have chance to apply this formula. to solve for the height. It might be worth pointing out that the answer in a. is basis dependent (that is, the value of the determinant depends on the bases chosen) and that b. addresses this shortcoming by 'tying' the $V,W$ bases together with $\phi$. For this, there are known formulas for Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line?

And actually, let's just solve Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? We introduce vectors and notation associated with vectors in standard position. We can just calculate the determinant of a 4 x 4 matrix using the "conventional" method, i.e. $\varphi(B)=\{\varphi v_1,\ldots,\varphi v_n\}$ is a basis of $W$, and the determinant is independent of the choice of $B$, provided that $Tu$ is analyzed in terms of $\varphi(B)$. The same dimension is needed so that you can take the determinant of the resulting matrix. Can the Spiritual Weapon spell be used as cover? not the same vector. But my reason for the claim is that if you do the "natural" thing, i.e. In this section, we give a recursive formula for the determinant of a matrix, called a cofactor expansion.The formula is recursive in that we will compute the determinant of an \(n\times n\) matrix assuming we already know how to compute the determinant of an \((n-1)\times(n-1)\) matrix.. At the end is a supplementary subsection write down a matrix for $T$ with respect to a basis $\mathcal{B}_1$ of $V$ and a basis $\mathcal{B}_2$ of $W$ and then take its determinant, then the answer depends on these choices. With $\dim{V}=\dim{W}$, I propose that one can write the matrix representation in two orthonormal basis and take the determinant of this matrix? It only takes a minute to sign up. Song Packs and Full Albums Sybreed - God is an Automaton. $$ Would the reflected sun's radiation melt ice in LEO?

What do the trace map and determinant map mean in this context? 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 $\varphi$. And then when I multiplied Regardless, your record of completion will remain.
