Power set. Universal set. Venn diagrams. Union and Intersection of sets. 2. Relations & Functions Ordered pairs. Cartesian product of sets. Number of elements in the Cartesian product of two finite sets. Cartesian product of the set of reals with itself ( R x R only).Definition of relation, pictorial diagrams, domain, co-domain and range of a relation. Function as a special type of relation. Pictorial representation of a function, domain, co-domain and range of a function. Real valued functions, domain and range of these functions, constant, identity, polynomial, rational, modulus, signum, exponential, logarithmic and greatest integer functions, with their graphs. Unit-II: Algebra 1. Complex Numbers and Quadratic Equations Need for complex numbers, especially√−1, to be motivated by inability to solve some of the quardratic equations. Algebraic properties of complex numbers. Argand plane. Statement of Fundamental Theorem of Algebra, solution of quadratic equations (with real coefficients) in the complex number system. 2. Sequence and Series Sequence and Series. Arithmetic Progression (A. P.). Arithmetic Mean (A.M.) Geometric Progression (G.P.), general term of a G.P., sum of n terms of a G.P., infinite G.P. and its sum, geometric mean (G.M.), relation between A.M. and G.M. Unit-III: Coordinate Geometry 1. Straight Lines Brief recall of two dimensional geometry from earlier classes. Slope of a line and angle between two lines. Various forms of equations of a line: parallel to axis, point -slope form, slope-intercept form, two-point form, intercept form and normal form. General equation of a line. Distance of a point from a line. Unit-IV: Calculus 1. Limits Intuitive idea of limit. Limits of polynomials and rational functions trigonometric, exponential and logarithmic functions Unit-V: Statistics and Probability 1. Statistics Measures of Dispersion: Range, mean deviation, variance and standard deviation of ungrouped/grouped data.

TERM II ( 2021 - 2022)

Unit-I: Sets and Functions 1. Trigonometric Functions Positive and negative angles. Measuring angles in radians and in degrees and conversion from one measure to another.

Introduction to Three-dimensional Geometry Coordinate axes and coordinate planes in three dimensions. Coordinates of a point. Distance between two points and section formula. Unit-IV: Calculus 1. Derivatives Derivative introduced as rate of change both as that of distance function and geometrically. Definition of Derivative, relate it to scope of tangent of the curve, derivative of sum, difference, product and quotient of functions. Derivatives of polynomial and trigonometric functions. Unit-V: Statistics and Probability 1. Probability Random experiments; outcomes, sample spaces (set representation). Events; occurrence of events, ‘not’, ‘and’ and ‘or’ events, exhaustive events, mutually exclusive events, Probability of an event, probability of ‘not’, ‘and’ and ‘or’ events.

The syllabus provides an overview of the Maths topics. Maths is a subject that requires daily practice. So knowing the syllabus will help students in creating a daily study plan. Students can easily keep a record of topics that they have completed. Students will feel confident during the exam as the question paper will be designed from the syllabus.
