some important math facts to know

In this chapter, we have seen how arranging numbers in orderly rows and columns under the guise of Matrices and Determinants, has helped to solve linear equations or find the area of a triangle. There are in fact other much wider applications in Science and Engineering and other fi..

Conclusion - We have seen the application of matrices and determinants in solving system of linear equation with three unknown variables. Matrices and determinants are also widely used in solving large system of linear equation. Some of these methods are Gauss-elimination method, Gauss-Jordan metho..

Note that we can also evaluate the determinant D 1 , D 2 and D 3 directly without using the properties of determinant. The solution of the system is given by It is important to mention here the consistency and inconsistency of a system of linear equations with three unknown..

Axioms : The self-evident truths or the basic facts which are accepted without any proof are called axiom..

We all know that 0°C is equivalent to 32°F. It is also a known fact that 100°C equals to 212°F. But at a particular temperature, both the Centigrade and the Fehrenheit scale show the same reading. Identify that temperature. => - 40 or 40 or - 30 or 30..
