In this video, we will get to learn about the Inverse of a Matrix and its Applications in solving the simultaneous equation. a) A is a matrix formed by all the coefficients in the system b) X is a ...

One of the fundamental operations in machine learning is computing the inverse of a square matrix. But not all matrices have an inverse. The most common way to check if a matrix has an inverse or not ...

Solution: det (A) = −5, and for n×n matrix adj (A) has determinant (det A)^ (n−1). Here n = 3, so det (B) = (−5)^ (2) = 25.
