Probability Introduction Probability is the measure of uncertainty of various phenomenons, numerically. It can have positive value from 0 to 1. The words ‘probably’, ‘doubt’, ‘most probably’, ‘chances’, etc., used in the statements above involve an element of uncertainty. Concept of Probability is used in insurance industry to calculate the premium; it is also used […]

Continue readingStatistics Statistics Statistics is the science of average & estimates. It is the study of collection, analysis, interpretation & Organization of data for specific purpose. We take decision with that data. Data: Everyday, we come across a wide variety of information in the form of facts, numerical figure, table groups etc. Eg: Information related […]

Continue readingSurface Areas Volumes Surface Area Volumes We will study Surface Area of a Combination of Solids, Volume of a Combination of Solids, Conversion of Solid from One Shape to Another & Frustum of a Cone . Some of the basic solids are Cylinder, Cuboid, Sphere and Cone. Surface Area & volumes of these basic […]

We generally take the value of π as 22/7 or 3.14 Area of Circle = π * Radius […]

Continue readingConstructions Constructions We will study How to divide a line segment in a given ratio Construct a triangle similar to given triangle Construct tangent to a circle Construction 1 : To divide a line segment in a given ratio Let’s divide a line AB in ration 2:3 Steps: Draw any ray AX, making an […]

Continue readingCircles Circles A circle is a collection of all points in a plane which are at a constant distance (radius) from a fixed point (centre). We will study Secant & Tangent Circles are used extensively in our day to day life. Car tyres, football, well, CD, DVDs etc is circular. Circles are used extensively […]

In fact, trigonometry is the study of relationships between the sides and angles of a triangle. Application of Trigonometry: Find height of tall building or tower without actually measuring it […]

In fact, trigonometry is the study of relationships between the sides and angles of a triangle. Application of Trigonometry Find height of tall building or tower without actually measuring it Find the height […]

Continue readingCoordinate Geometry Coordinate Geometry To locate the position of a point on a plane, we require a pair of coordinate axes. The distance of a point from the y-axis is called its x-coordinate, or abscissa. The distance of a point from the x-axis is called its y-coordinate, or ordinate. The coordinates of a point on […]

Continue readingTriangles Triangle Triangles Triangle is derived from word Tri meaning three & Angle, implies 3 angles. It is a closed figure formed by 3 intersecting lines. It has 3 sides, 3 angles, 3 vertices. Triangle is used in various fields Surveyor use it to find height of building It is used in construction of […]
