Learn Chapter 3 Matrices of Class 12 free with solutions of all NCERT Questions including Examples and Exercises.  

In this chapter, we learn

  • What a matrix is, how we form it and what is its order
  • Then we see different types of matrix like Square matrix, Zero matrix, Identity Matrix, Row Matrix, Column Matrix etc.
  • If two matrices are equal, then how to find its elements
  • How to add and subtract matrices,
  • And their Statement questions
  • Then how to multiply the matrices, keeping in mind their order
  • And its statement questions
  • How to solve a x + y, or an x + y + z equation using matrices
  • Then, finding an element when some equation is given
  • Or, finding a whole matrix when some equation is given
  • What is a Transpose of a Matrix, and its order
  • Then, What are Symmetric and skew symmetric matrices... and how to represent any matrix as a sum of symmetric and skew symmetric matrix
  • Then, doing some proof questions using Transpose property - (AB)' = B'A'
  • And finding Inverse of a matrix using elementary Transformation. Please check all of its questions. Specially the ones marked important
  • And then, finally, there are some questions on proof using Mathematical Induction
