Important Points to Remember – Class 11 Maths

• Sets are well-defined collections of objects where membership can be clearly determined, forming the foundation for modern mathematics as developed by Georg Cantor (1845-1918)
• A complex number is written as a + ib where ‘a’ is the real part (Re z) and ‘b’ is the imaginary part (Im z), with i = √(-1)
• Two complex numbers z₁ = a + ib and z₂ = c + id are equal if and only if a = c and b = d
• Cartesian product P × Q is the set of all ordered pairs (p,q) where p ∈ P and q ∈ Q
• Trigonometric functions are generalizations of trigonometric ratios studied in earlier classes for acute angles only
• Angles measured anticlockwise are positive while angles measured clockwise are negative from the initial side to terminal side
• Relations involve pairs of objects in certain order, while functions are special relations with mathematically precise correspondence
• The equation x² + 1 = 0 has no real solution, necessitating the introduction of complex numbers in CBSE 2025-26 curriculum
• Set notation uses symbols like N (natural numbers), Z (integers), Q (rational numbers), and R (real numbers)
• Trigonometry derives from Greek words ‘trigon’ (triangle) and ‘metron’ (measuring), originally used for navigation and surveying
• Complex number addition follows the rule: (a + ib) + (c + id) = (a + c) + i(b + d)
• One complete revolution represents 360° or 2π radians as fundamental angle measurement units
• Ordered pairs in Cartesian products maintain specific sequence, making (p,q) different from (q,p)
• Arya Bhatta (476-550 CE) made significant contributions to trigonometry as mentioned in NCERT textbooks
• Set theory applications extend to geometry, sequences, probability, relations, and functions in Class 11 mathematics

Quick Revision Notes – Class 11 Maths

• Remember that sets can be represented in three ways: roster form {1,3,5,7,9}, set-builder form {x: x is odd, x < 10}, and Venn diagrams for visual representation
• For complex numbers, always separate real and imaginary parts when solving equations; equate real parts with real parts and imaginary parts with imaginary parts
• In trigonometric functions, memorize that angles can be measured in degrees, radians, and gradians with conversion formulas being crucial for board exams
• Cartesian products are not commutative: A × B ≠ B × A unless A = B, which frequently appears in CBSE objective questions
• When working with sets, focus on subset relationships, proper subsets, universal sets, and complement operations for comprehensive understanding
• Complex number operations follow real number algebra rules with the additional property that i² = -1, i³ = -i, i⁴ = 1
• Trigonometric identities from Class 10 remain valid and form the foundation for Class 11 trigonometric functions and their properties
• Relations can be represented using arrow diagrams, ordered pairs, or matrices – practice all three methods for board exam preparation
• Set operations include union (∪), intersection (∩), difference (-), and complement (‘) with specific properties and De Morgan’s laws
• Functions require each element in domain to have exactly one image in codomain, distinguishing them from general relations
• Complex plane representation uses horizontal axis for real parts and vertical axis for imaginary parts, similar to coordinate geometry
• Radian measure is often preferred in calculus and higher mathematics; π radians = 180° is the fundamental conversion
• Empty set (∅) and universal set (U) have special properties in set operations and appear frequently in CBSE board questions
• Trigonometric functions of allied angles and negative angles follow specific patterns that simplify complex problems
• Domain and range concepts for relations and functions connect directly to set theory, making comprehensive study essential
