Topics

1

Real Number

Euclid’s division lemma, Fundamental Theorem of Arithmetic-statements after reviewing work done earlier and after illustrating and motivating through examples. Proofs of results-irrationality of square root 2, 3, and 5 decimal expansions of rational numbers in terms of terminating/non-terminating recurring decimals.

2

Polynomial

Zeros of a polynomial. Relationship between zeros and coefficients of a polynomial with particular reference to quadratic polynomials. Statement and simple problems on division algorithm for polynomials with real coefficients

3

Pair of Linear Equations in 2 variables

Pair of linear equations in two variables. Geometric representation of different possibilities of solutions/ inconsistency. Algebraic conditions for number of solutions. Solution of pair of linear equations in two variables algebraically by substitution, by elimination and by cross multiplication. Simple situational problems must be included. Simple problems on equations reducible to linear equations may be included.

4

Quadratic Equations

Standard form of a quadratic equation ax2 + bx + c = 0, (a ¹ 0). Solution of quadratic equations (only real roots) by factorization and by completing the square, i.e. by using quadratic formula. Relationship between discriminant and nature of roots. Problems related to day-to-day activities to be incorporated.

5

Arithmetic Progression

Motivation for studying A.P. Derivation of standard results of finding the nth terms and sum of first n terms.

6

Introduction to Trigonometry

Trigonometric ratios of an acute angle of a right-angled triangle. Proof of their existence (well defined); motivate the ratios, whichever are defined at 00 and 900. Values (with proof) of the trigonometric ratios of 300, 450 and 600. Relationship between the ratios. Trigonometric Identities: Proof and applications of the identity sin2 A + cos2A=1, sec2A - tan2A=1, cosec2A - cot2A = 1. Only simple identities to be given. Trigonometric ratios of complementary angles

7

Heights and Distances (Not from examination point of view)

Simple and believable problems on heights and distances. Problems should not involve more than two right triangles. Angles of elevation/depression should be only 30, 45, 60 degree.

8

Lines (In two-dimensions)

Review the concepts of coordinate geometry done earlier including graphs of linear equations. Awareness of geometrical representation of quadratic polynomials. Distance between two points and section formula (internal). Area of a triangle.

9

Triangles

Definitions, examples, counter examples of similar triangles. i) (Prove) If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio. ii) (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side. iii) (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar. iv) (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and two triangles are similar. v) (Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar. vi) (Motivate) If a perpendicular is drawn from the vertex of the right angle to the hypotenuse, the triangles on each side of the perpendicular are similar to the whole triangle and to each other. vii) (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares on their corresponding sides. viii) (Prove) In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. ix) (Prove) In a triangle, if the square of one side is equal to sum of the squares of the other two sides, the angle opposite to the first side is a right triangle.

10

Circles

Tangent to a circle at any point on it is motivated by chords drawn from points coming closer and closer to the point. i) (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact. ii) (Prove) The lengths of tangents drawn from an external point to a circle are equal.

11

Constructions

i) Division of a line segment in a given ratio (internally). ii) Tangent to a circle from a point outside it. iii) Construction of a triangle similar to a given triangle.

12

Area Related to Circle

Motivate the area of a circle; area of sectors and segments of a circle. Problems based on areas and perimeter/circumference of the above-said plane figures. (In calculating area of segment of a circle, problems should be restricted to central angle of 60, 90, and 120 degreeonly. Plane figures involving triangles, simple quadrilaterals and circle should be taken.)

13

Surface Areas and Volumes

i) Problems on finding surface areas and volumes of combinations of any two of the following: cubes, cuboids, spheres, hemispheres and right circular cylinders/cones. Frustum of a cone. ii) Problems involving converting one type of metalic solid into another and other mixed problems. (Problems with combination of not more than two different solids be taken.)

14

Statistics

Mean, median and mode of grouped data (bimodal situation to be avoided). Cumulative frequency graph.

15

Probabilities

Classical definition of probability. Connection with probability as given in Class IX. Simple problems on single events, not using set notation.
