- 线性代数 （det)是什么意思？ - 百度知道
线性代数 （det)是什么意思？A矩阵的行列式（determinant），用符号det(A)表示。行列式在数学中，是由解线性方程组产生的一种算式其定义域为nxn的矩阵 A，取值为一个标量，写作det(A)或 | A | 。

- linear algebra - Why is $\det (-A)= (-1)^n\det (A)$? - Mathematics . . .
Typically we define determinants by a series of rules from which $\det(\alpha A)=\alpha^n\det(A)$ follows almost immediately Even defining determinants as the expression used in Andrea's answer gives this right away On the other hand, the arguments showing $\det(AB)=\det(A)\det(B)$ are more elaborate $\endgroup$ –
- linear algebra - How do I prove that $\det A= \det A^T$? - Mathematics . . .
Note that the best way of proving that $\det(A)=\det(A^t)$ depends very much on the definition of the determinant you are using My personal favorite way of proving it is by giving a definition of the determinant such that $\det(A)=\det(A^t)$ is obviously true
- prove that $\\det(ABC) = \\det(A) \\det(B) \\det(C)$ [for any $n×n . . .
I was thinking about trying to argue because the numbers of a given matrix multiply as scalars, the determinant is the product of them all and because the order of the multiplication of det(ABC) stays the same, det(ABC) = det(A) det(B) det(C) holds true
