RD Sharma Class 12 Solutions Adjoint and Inverse of a Matrix (Ex 7.1) Exercise 7.1

Mathematics has developed as the result of the curious human intellect, much like most other subjective and objective sciences. As students, sometimes we might feel frustrated with the number of equations, formulae, and theorems we have to memorize and apply. However, we must realize that this entire knowledge was developed by geniuses who were students themselves, of the universe around us. 

Thus when you study a subject, any subject - approach it with a curious mind and not simply to score high. It will take a student a long way in all their pursuits. This is the Indic way of looking at knowledge and knowledge systems. It is then no wonder that we have been developing and applying concepts of Arithmetic and Trigonometry before the entire world even heard of them. To make such achievements is the highest goal of every Indian student! 

Matrices as we know are an ordered rectangular arrangement of a list of items, usually numbers or variables. The adjoint or adjugate of a matrix is the transpose of the cofactor matrix for that particular matrix. The inverse of a matrix is when, say a matrix B is multiplied by that matrix itself gives an identity matrix that can be codified as B raised to -1.
