Formula Sheet — Matrices

Important formulas and equations from Matrices for AP EAPCET Mathematics.

Formulas — Matrices

Matrix Fundamentals

A = [aᵢⱼ]ₘₓₙ
Order of matrix = m × n

Special Types of Matrices

Diagonal Matrix: aᵢⱼ = 0 for i ≠ j
Scalar Matrix: aᵢⱼ = k for i = j, aᵢⱼ = 0 for i ≠ j
Identity Matrix: aᵢⱼ = 1 for i = j, aᵢⱼ = 0 for i ≠ j

Matrix Operations

A + B = [aᵢⱼ + bᵢⱼ]
A - B = [aᵢⱼ - bᵢⱼ]
kA = [kaᵢⱼ]
AB = [Σⱼ aᵢⱼbⱼₖ] for (i,k)th element

Transpose of Matrix

A' = [bⱼᵢ] where bⱼᵢ = aᵢⱼ
(A + B)' = A' + B'
(AB)' = B'A'
(A')' = A
