Discover the essential condition a square matrix must meet to be invertible in this concise guide. A square matrix A is invertible if and only if its determinant is not zero, i.e., |A| ≠ 0. This is crucial because the inverse of a matrix is given by A^-1 = 1/|A|(adj A), which requires |A| to be non-zero. Perfect for 12th-grade students ...

The climax of linear algebra imo

We learned about matrix multiplication, so what about matrix division? There is no such thing! But we can multiply a matrix by its inverse, which is kind of like multiplying a number by its reciprocal, to cancel it out, which with matrices will yield the identity matrix. So how do you find an inverse matrix? Let's learn how! Watch the whole ...

A square matrix that is not invertible is called singular or degenerate. A square matrix is singular if and only if its determinant is zero. Singular matrices are rare in the sense that if a square matrix's entries are randomly selected from any finite region on the number line or complex plane, the probability that the matrix is singular is 0 ...
