(iii) A square matrix is called skew-symmetric ifAT=−A. Prove that if A and B are skew-symmetric matrices, then A + B is skew-symmetric. Transposed Matrix: A mxn A AT A Here are some properties: (AT)T=A (A+...
解析 Solution: A be a square matrixlet, B=A-A^TNow,(split)B^T&=A^T-(A^T)^T\&=A^T-A\&=-(A-A^T)\&=-B(split)as B^T=-B then B ie, A-A^T is a skew-symmetric matrix.Hence A-A^T is a skew-symmetric matrix....

A=(bmatrix) -2&-1 3&2(bmatrix) 相关知识点: 试题来源: 解析 the multiplicative inverse of A. In problem, in both parts, A^(-1)=A and A^2=I. One could conclude that if A is a square matrix where A=A^(-1) then A^2=I A^2=A⋅ A=A⋅ A^(-1)=I; A^(...
The correct Answer is:C To solve the problem, we need to find the value of A−1 given that A3=I, where I is the identity matrix. 1. Understanding the Given Equation: We start with the equation: A3=I This means that if we multiply the matrix A by itself three times, we get the...
