For the purpose of this article, we will stick to square matrices of the order 1, 2, and 3 only.Identity Matrix This is a special type of square matrix where the values of a square matrix, other than its diagonal, are zeros. Below we show identity matrices of order 1, 2, and 3....
If A is a square matrix such thatA2=I, then(A−I)3+(A+I)3-7A is equal to View Solution Free Ncert Solutions English Medium NCERT Solutions NCERT Solutions for Class 12 English Medium NCERT Solutions for Class 11 English Medium
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...

Identity Matrix: It is a square matrix and has ones as its diagonal elements, and all the other elements are zeros. Scalar Matrix: A square matrix having the same number as all its diagonal elements and all the other elements are equal to zero. Symmetric Matrix: A matrix whose transpose ...
How does one square a 3x3 matrix? A 3x3 matrix is calculated by multiplying the matrix by itself. The dot product of the matrices must be performed in order to receive the answer. In this process, the 1st entry in the first row of the first matrix must multiply the first entry of the...
