Important Points to Remember – Class 12 Maths

• Relations are defined as arbitrary subsets of A × B, where A and B are sets, and functions are special types of relations
• For inverse functions to exist, the original function must be both one-one (injective) and onto (surjective)
• Trigonometric functions are restricted to specific domains to make them invertible: sin^(-1) has domain [-1,1] and range [-π/2, π/2]
• A matrix is a rectangular array of numbers arranged in rows and columns, denoted by [aij] where i represents row and j represents column
• Matrix multiplication is possible only when the number of columns in first matrix equals the number of rows in second matrix
• For a square matrix A of order n, the determinant is a unique number associated with it, denoted as |A| or det(A)
• A 2×2 matrix determinant is calculated as |A| = a₁b₂ – a₂b₁ for matrix [[a₁,b₁],[a₂,b₂]]
• The system of linear equations has a unique solution if and only if the determinant of coefficient matrix is non-zero
• Identity matrix I has all diagonal elements as 1 and all non-diagonal elements as 0
• Two matrices can be added or subtracted only if they have the same order (same number of rows and columns)
• The transpose of matrix A, denoted as A’, is obtained by interchanging rows and columns
• A matrix is called singular if its determinant is zero, and non-singular if its determinant is non-zero
• For composition of functions (fog)(x) = f(g(x)), the domain is the set of all x where g(x) is defined and f(g(x)) exists
• Principal value branches are used for inverse trigonometric functions to ensure they remain functions
• Matrix applications include solving linear equations, cryptography, computer graphics, and economic modeling as per CBSE 2025-26 curriculum

Quick Revision Notes – Class 12 Maths

• Remember the difference between relations and functions: all functions are relations, but not all relations are functions – this concept builds from Class XI and is crucial for board exams
• For inverse trigonometric functions, memorize the restricted domains: sin⁻¹[-1,1], cos⁻¹[-1,1], tan⁻¹(all real numbers) – questions worth 4-6 marks appear regularly
• Matrix operations follow specific rules: addition is commutative but multiplication is not commutative (AB ≠ BA in general) – common mistake in board exams
• When solving determinants, use properties like R₁ → R₁ + kR₂ to simplify calculations – saves time in 4-mark questions
• For 3×3 determinants, expansion along first row is most common, but choose the row/column with maximum zeros for efficiency
• Cramer’s rule works only when determinant of coefficient matrix is non-zero – essential for solving linear equations
• Practice identifying one-one and onto functions through graphs – horizontal and vertical line tests respectively
• Matrix inverse exists only for square matrices with non-zero determinant – A⁻¹ = (1/|A|) × adj(A)
• Cofactor expansion technique: C₁₁ = (-1)¹⁺¹ × M₁₁ where M₁₁ is the minor – sign pattern is crucial
• Adjoint of matrix A is transpose of cofactor matrix – adj(A) = [Cᵢⱼ]ᵀ
• Use properties of determinants to solve faster: if two rows/columns are identical, determinant is zero
• Binary operations must satisfy closure property within the given set – check this first in operation problems
• For inverse functions, range of f⁻¹ equals domain of f and vice versa – graphically, they’re reflections about y = x line
• Matrix word problems often involve cost analysis or transformation geometry – read questions carefully for proper matrix setup
