## CBSE Class 10 Maths Chapter 15 Probability Notes

Probability: It is the numerical measurement of the degree of certainty. Theoretical probability associated with an event E is defined as “If there are ‘n’ elementary events associated with a random experiment and m of these are favourable to the event E then the probability of occurrence of an event is defined by P(E) as the […]

## CBSE Class 10 Maths Chapter 14 Statistics Notes

MEAN (AVERAGE): Mean [Ungrouped Data] – Mean of n observations, x1, x2, x3 … xn, is MEAN [Grouped Data]: The mean for grouped data can be found by the following three methods: (i) Direct Mean Method: Class Mark = Note: Frequency of a class is centred at its mid-point called class mark. (ii) Assumed Mean Method: In this, an […]

## CBSE Class 10 Maths Chapter 13 Surface Areas and Volumes Notes

SURFACE AREA AND VOLUME OF COMBINATIONS Cone on a Cylinder. r = radius of cone & cylinder; h1 = height of cone h2 = height of cylinder Total Surface area = Curved surface area of cone + Curved surface area of cylinder + area of circular base = πrl + 2πrh2 +πr2; Slant height, l = Total Volume […]

## CBSE Class 10 Maths Chapter 12 Areas related to Circles Notes

Circumference of a circle = 2πr Area of a circle = πr2 …[where r is the radius of a circle] Area of a semi-circle = Area of a circular path or ring: Let ‘R’ and ‘r’ he radii of two circles Then area of shaded part = πR2 – πr2 = π(R2 – r2) = π(R + r)(R – […]

## CBSE Class 10 Maths Chapter 11 Constructions Notes

Determining a Point Dividing a given Line Segment, Internally in the given Ratio M : N Let AB be the given line segment of length x cm. We are required to determine a point P dividing it internally in the ratio m : n. Steps of Construction: Draw a line segment AB = x cm. […]

## CBSE Class 10 Maths Chapter 10 Circles Notes

Circle: A circle is a collection of all points in a plane which are at a constant distance from a fixed point. Centre: The fixed point is called the centre. Radius: The constant distance from the centre is called the radius. Chord: A line segment joining any two points on a circle is called a chord. Diameter: A chord passing […]

## CBSE Class 10 Maths Chapter 9 Some Applications of Trigonometry Notes

Line of Sight When an observer looks from a point E (eye) at an object O then the straight line EO between the eye E and the object O is called the line of sight. Horizontal When an observer looks from a point E (eye) to another point Q which is horizontal to E, then […]

## CBSE Class 10 Maths Chapter 8 Introduction to Trigonometry Notes

Position of a point P in the Cartesian plane with respect to co-ordinate axes is represented by the ordered pair (x, y). Trigonometry is the science of relationships between the sides and angles of a right-angled triangle. Trigonometric Ratios: Ratios of sides of right triangle are called trigonometric ratios. Consider triangle ABC right-angled at B. […]

## CBSE Class 10 Maths Chapter 7 Coordinate Geometry Notes

Position of a point P in the Cartesian plane with respect to co-ordinate axes is represented by the ordered pair (x, y). The line X’OX is called the X-axis and YOY’ is called the Y-axis. The part of intersection of the X-axis and Y-axis is called the origin O and the co-ordinates of O are […]

## CBSE Class 10 Maths Chapter 6 Triangles Notes

SIMILAR FIGURES Two figures having the same shape but not necessary the same size are called similar figures. All congruent figures are similar but all similar figures are not congruent. SIMILAR POLYGONS Two polygons are said to be similar to each other, if: (i) their corresponding angles are equal, and (ii) the lengths of their […]

## CBSE Class 10 Maths Chapter 5 Arithmetic Progressions Notes

SEQUENCE: A sequence is an arrangement of numbers in a definite order and according to some rule. Example: 1, 3, 5,7,9, … is a sequence where each successive item is 2 greater than the preceding term and 1, 4, 9, 16, 25, … is a sequence where each term is the square of successive natural numbers. […]

## CBSE Class 10 Maths Chapter 4 Quadratic Equations Notes

A quadratic polynomial of the form ax² + bx + c, where a ≠ 0 and a, b, c are real numbers, is called a quadratic equation when ax² + bx + c = 0. Here a and b are the coefficients of x² and x respectively and ‘c’ is a constant term. Any value […]

## CBSE Class 10 Maths Chapter 3 Pair of Linear equations in Two Variables Notes

For any linear equation, each solution (x, y) corresponds to a point on the line. General form is given by ax + by + c = 0. The graph of a linear equation is a straight line. Two linear equations in the same two variables are called a pair of linear equations in two variables. […]

## CBSE Class 10 Maths Chapter 2 Polynomials Notes

“Polynomial” comes from the word ‘Poly’ (Meaning Many) and ‘nomial’ (in this case meaning Term)-so it means many terms. A polynomial is made up of terms that are only added, subtracted or multiplied. A quadratic polynomial in x with real coefficients is of the form ax² + bx + c, where a, b, c are […]
