Important formulas and equations from Determinants for IPU CET Mathematics.

Formulas — Determinants

Basic Definitions and Order Determinants

|A| = a (for 1×1 matrix A = [a])
|A| = a₁₁a₂₂ - a₁₂a₂₁
|A| = a₁₁(a₂₂a₃₃ - a₂₃a₃₂) - a₁₂(a₂₁a₃₃ - a₂₃a₃₁) + a₁₃(a₂₁a₃₂ - a₂₂a₃₁)
|kA| = kⁿ|A|

Properties of Determinants

|Aᵀ| = |A|
|AB| = |A| × |B|
|A⁻¹| = 1/|A|

Area of Triangle Using Determinants

Area = (1/2)|x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂)|
Area = (1/2)|det([x₁ y₁ 1; x₂ y₂ 1; x₃ y₃ 1])|

Adjoint and Inverse of Matrix

adj(A) = [Cᵢⱼ]ᵀ
A⁻¹ = (1/|A|) × adj(A)
A × adj(A) = |A| × I
|adj(A)| = |A|ⁿ⁻¹
