In this video I will teach you how you can show that a given matrix is invertible. In this video I will do a worked example of a 3x3 matrix and explain the procedure for showing that a 2x2 matrix is invertible as well. Fundamentally the test for invertibility is the determinant. This method can also be used to show that a matrix is singular (i ...

An invertible matrix is a matrix that has an inverse. In this video, we investigate the relationship between a matrix's determinant, and whether that matrix is invertible.

Invertible Matrices are an algebraic concept that helps us solve Linear Systems of Equations. Invertible Transformations are a geometric concept where we can "undo" a transformation. But in fact they coincide! In this video, we prove that if you have an invertible matrix, the transformation it defines is also invertible. Likewise, if you have ...

In this tutorial I will teach you how you can show that a matrix is symmetric using a very simple technique. Fundamentally a matrix is symmetric if it is equal to its transpose (i.e. A= AT)

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 ...

The inverse of matrix is another matrix, which on multiplication with the given matrix gives the multiplicative identity. For a matrix A, its inverse is A⁻¹, and A.A⁻¹ = I. We can calculate the Inverse of a Matrix by: Step 1: calculating the Matrix of Minors, Step 2: then turn that into the Matrix of Cofactors, Step 3: then the Adjugate ...
