Definition of Determinants- 

Determinants can be defined as the scalar quantity which is obtained from the sum of products of the element in a Square Matrix according to the prescribed rule.

  • It is helpful in finding the adjoint and inverse of a Matrix.

  • They act as a scaling factor for Matrices. 

Some of the fundamental properties of Determinants are as follows: 

  • For an identity Matrix, the determinant is always counted as one.

  • One of the important properties of a Determinant is that it always remains unaltered; this means that if we change the rows to columns or vice Versa still the Determinant would remain the same.

  • While calculating the Determinant for an element if all the elements are in a room all the column of concern is zero which results in the overall Determinant being zero as well.

  • While calculating the Determinant if we interchange any two rows for columns for that sake the resultant Determinant sign also changes.

  • While calculating the Determinants for two sets of rows or columns,  if all the elements of row 1 show proportionality to all the elements of row 2 then the resultant Determinant is zero.

  • In cases where all the elements in a row or column calculation of a Determinant are multiplied by a non-zero constant result in the Determinant which gets multiplied by the same constant.

FAQs on RD Sharma Class 12 Solutions Chapter 6 - Determinants (Ex 6.5) Exercise 6.5

1. Can I repeat all the questions from RD Sharma during the exam?

If you have gone through all the questions from RD Sharma way prior to the exam, the technique to re-practice the important question is to mark the question which you find difficult or conceptually enlightening with a highlighter so that it's easy for your eye to catch those particular question from all the pool of question. And then all you can do is practice those particular questions on the day before the examination. If you sit with the whole RD Sharma a day before the exam it would lead to a panic stage as you might not be able to solve all the questions and not being able to solve those questions would leave you in a panic stage.

So in my particular opinion don’t go with all the questions of RD Sharma a day before the examination.
