## Knowledge in UPSC- IES/ISS

Study material on Linear algebra

This material is all about Cayley Hamilton theorem and its implementation. Which is used to find eigen values and vectors . It is also used to find diagonalisation of Matrices.

This module is about finding associated matrix for the quadratic equation. This also tells about if the quadratic form is positive definite, positive semi definite, negative definite, negative semi definite and indefinite.
