In this video, you will learn how to find the sum and product of eigen values from a given matrix without finding its eigen values.
These are important results help to solve various problems
the shortcut to find the characteristic equation of a 2 x 2 matrix. The roots of a characteristic equation are called eigen values. For 2 x 2 matrix, the characteristic equation is quadratic and there are various methods to solve quadratic equation easily. Hence, you can find the characteristic roots or eigen values very quickly. So, watch the video, learn from it and apply the short cut for the questions given at the end of the video.
In the next video, I will teach you the short cut to write the characteristic equation for a 3 x 3 matrix. I will also upload videos on eigen vector and various properties of eigen values.
I have uploaded videos on various topics related to matrices. The link of the playlist is given below:
• Matrix, Linear Algebra
