Understanding Singular Matrices | PreCalculus

What are singular matrices and what does a singular matrix mean are a few of the questions explored in this video. A singular matrix is a square matrix that cannot be inverted, this means that there is not a unique solution to the linear system of equations. Through visualizing what the determinant of a matrix is I hope to aid students gain a intuition about what the determinant of a matrix is.

The following timeline is meant to aid your understanding of Singular Matrices:

Thanks for making this clear and concise. Appreciate not having to watch a 30 minute video to get that quick bit of info.

Wow! I have taken a linear algebra class but no one gave me an intuitive explanation of the determinant like this.
