Important Points to Remember – Class 12 Maths

• Relations and Functions (Chapter 1) covers different types of relations including reflexive, symmetric, transitive, and equivalence relations as per NCERT 2025-26 syllabus
• A function f is invertible if and only if it is both one-one (injective) and onto (surjective), making f^(-1) exist
• Inverse Trigonometric Functions (Chapter 2) are defined only on restricted domains to ensure they are one-one and onto
• The principal value branch of sin^(-1)x lies in [-π/2, π/2] and cos^(-1)x lies in [0, π] according to NCERT guidelines
• Matrix (Chapter 3) is a rectangular arrangement of numbers arranged in rows and columns, denoted by capital letters A, B, C
• Two matrices can be added or subtracted only when they have the same order (same number of rows and columns)
• Matrix multiplication AB is possible only when number of columns in A equals number of rows in B
• A square matrix A is invertible if and only if |A| ≠ 0, where |A| represents the determinant of matrix A
• Determinant (Chapter 4) of a square matrix is a unique number associated with every square matrix
• For a 2×2 matrix A = [a b; c d], the determinant |A| = ad – bc
• Cramer’s rule can be used to solve system of linear equations when the coefficient matrix has non-zero determinant
• The area of triangle with vertices (x₁,y₁), (x₂,y₂), (x₃,y₃) can be found using determinants as per NCERT formula
• Cofactor of element aᵢⱼ in a matrix is (-1)^(i+j) times the minor Mᵢⱼ
• Adjoint of a matrix A is the transpose of the cofactor matrix of A
• For CBSE Board 2025-26, Mathematics carries 80 marks with these four chapters being crucial for scoring well

Quick Revision Notes – Class 12 Maths

• Remember the mnemonic "RESTE" for types of relations: Reflexive, Equivalence, Symmetric, Transitive, Empty relation types
• For inverse trigonometric functions, always check the domain and range restrictions before solving problems
• Practice graphical representation of inverse trig functions as they frequently appear in CBSE board exams with 4-6 marks
• Matrix operations follow specific order: Addition/Subtraction → Scalar Multiplication → Matrix Multiplication → Finding Inverse
• To find inverse of 2×2 matrix quickly: swap diagonal elements, change signs of off-diagonal elements, divide by determinant
• Sarrus rule for 3×3 determinants: write first two columns again and calculate products diagonally (positive and negative)
• Properties of determinants help simplify calculations: |AB| = |A||B|, |A^T| = |A|, |kA| = k^n|A| for n×n matrix
• For solving linear equations using matrices, always check if coefficient matrix is non-singular (determinant ≠ 0)
• Minors and cofactors pattern: sign changes in checkerboard pattern starting with positive at (1,1) position
• Applications of determinants include finding area of triangles, solving linear equations, and checking consistency of systems
• For CBSE marking scheme, show all steps clearly in matrix and determinant problems to get full marks
• Important properties to memorize: (AB)^(-1) = B^(-1)A^(-1), (A^T)^(-1) = (A^(-1))^T, (A^(-1))^(-1) = A
• Composite functions: (fog)(x) = f[g(x)] – always work from inside to outside when evaluating
• Binary operations must satisfy closure, associativity, identity element, and inverse element properties for being a group
• Time management tip for boards: Determinant problems typically take 6-8 minutes, matrix problems 8-10 minutes each
