Matrices: Class 12 Mathematics (MP Board) important questions and practice
Matrices is chapter 3 of 13 in MP Board Class 12 Mathematics. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Types of matrices and equality of matrices
- Operations: addition, scalar multiplication, multiplication and their properties
- Transpose, symmetric and skew-symmetric matrices
- Expressing a matrix as the sum of symmetric and skew-symmetric matrices
- Invertible matrices and uniqueness of inverse (elementary row operations removed)
What examiners usually ask
- If A = [[1, 2], [3, 4]], find A^2 - 5A + 7I
- Express the matrix A = [[3, 5], [1, -1]] as the sum of a symmetric and a skew-symmetric matrix
- Find x and y if 2[[1, 3], [0, x]] + [[y, 0], [1, 2]] = [[5, 6], [1, 8]]
Exam tip
Matrix multiplication is not commutative, so keep the order of multiplication in every step; the symmetric-plus-skew-symmetric decomposition uses P = (A + A')/2 and Q = (A - A')/2 and is asked almost every year.
