The video tutorial explains how to find the greatest value of Lambda that makes a matrix singular. It begins by defining a singular matrix and the role of the determinant. The tutorial then demonstrates how to calculate the determinant of a 2x2 matrix and solve the resulting quadratic equation. Finally, it identifies the greatest value of Lambda that results in a singular matrix, emphasizing the process of finding eigenvalues.

What is a singular matrix?

• A matrix with all zero elements

• A matrix with a non-zero determinant

• A matrix that is invertible

• A matrix with a determinant of zero
