Many university STEM major programs have reduced the credit hours for a course in Matrix Algebra or have simply dropped the course from their curriculum. The content of Matrix Algebra in many cases is taught just in time where needed. This approach can leave a student with many conceptual holes in the required knowledge of matrix algebra.
In this series of blogs, we bring to you ten topics that are of immediate and intermediate interest for Matrix Algebra.
Here is the fourth topic
where we talk about unary operations on a matrix including transpose, symmetry, determinant, and trace of a matrix. Methods of finding determinants along with some fundamental theorems of determinants are discussed. Get all the resources in form of textbook content, lecture videos, multiple choice test, problem set, and PowerPoint presentation.

The time it would take to find the determinant of a matrix using the cofactor method can be daunting. A student may not realize this as they may be limited to finding determinants of matrices of order 4×4 or less by hand. In this blog, we derive the formula for a typical amount of computational time it would take to find the determinant of a nxn matrix using the cofactor method.
