Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.[1][2] In applying statistics to, e.g., a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal". Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.
When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples.

DATA ANALYSIS
Data analysis, also known as analysis of data or data analytics, is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.
Data mining is a particular data analysis technique that focuses on modeling and knowledge discovery for predictive rather than purely descriptive purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing on business information.
DIFFERENTIAL EQUATION
A differential equation is a mathematical equation that relates some function with its derivatives. In applications, the functions usually represent physical quantities, the derivatives represent their rates of change, and the equation defines a relationship between the two. Because such relations are extremely common, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology.
In pure mathematics, differential equations are studied from several different perspectives, mostly concerned with their solutions—the set of functions that satisfy the equation.
TELEVISION HISTORY
The invention of the television was the work of many individuals in the late 19th century and early 20th century. Individuals and corporations competed in various parts of the world to deliver a device that superseded previous technology. Many were compelled to capitalize on the invention and make profit, while some wanted to change the world through visual and audio communication technology.

KNOWLEDGE
Knowledge is a familiarity, awareness, or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning. Knowledge can refer to a theoretical or practical understanding of a subject.
It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); it can be more or less formal or systematic.[1] In philosophy, the study of knowledge is called epistemology; the philosopher Plato famously defined knowledge as "justified true belief", though this definition is now thought by some analytic philosophers[citation needed] to be problematic because of the Gettier problems while others defend the platonic definition.[2] However, several definitions of knowledge and theories to explain it exist.

MATRIX

*Today i am teaching class Matrix.
The definition is motivated by linear equations and linear transformations on vectors, which have numerous applications in applied mathematics, physics, and engineering.[1][2] In more detail, if A is an n × m matrix and B is an m × p matrix, their matrix product AB is an n × p matrix, in which the m entries across a row of A are multiplied with the m entries down a column of B and summed to produce an entry of AB.
When two linear transformations are represented by matrices, then the matrix product represents the composition of the two transformations.

Fraçtions
In the earlier classes we have learnt about fractions which included proper,improper and mixed fractions as well as their addition and subtraction.
Data handling
Today i am teaching class data handling.
Introduction
Data handling is a part of statistics.The word statistics is derived from the Latin word status.Like Mathematics statistics is also a science of numbers.The numbers referred to here are data expressed in numerical from like
1) Mark's of students in a class.
2) Weight of children of particular age in a village.
3) The amount of rainfall in a region over a period of years.
Mirror of symmetry
Today i am teaching class mirror symmetry.
Mirror line symmetry
When we look into a mirror we see our image is behind the mirror.The image is due to reflection in the mirror.We know that the image is formed as far behind the mirror as the object is in front of it.
In the figure if a mirror is placed along the line at the middle the half part of the figure reflects through the mirror creating the remaining identical half.
Line of symmetry
Today i am teaching types of symmetry.
Types of symmetry
1. Line of symmetry
2.Mirror of symmetry
3.Rotational symmetry.
1.Line of symmetry
When a line divides a given figure into two equal halves such that The left and right halves matchesexactly then we say that the figure is symmetrical about the line.This line is called the line of symmetry or axis of symmetry.
Symmetry
Today I am teaching symmetry.
Symmetry
Symmetry is an important geometrical concept commonly seen in nature and is used in every field of our life.
Artists Manufacturers designers architects and others make use of the idea of symmetry.The beehives flowers tree leaves hand kerchief utensils have symmetrical design.
For example if we cut an Apple into two equal halves we observe that two parts are in symmetry.
Rhombus
Today I am teaching construction of a rhombus.
Construction of a rhombus
I explain rhombus is constructed by splitting the figure into suitable triangles.First a triangle is constructed from the given data and then the fourth vertex is found.We need two independent measurements to construct a rhombus.
We can construct a rhombus when the following measurements are given
1.One side and one diagonal.
2.Two diagonal.
3.One side and one angle.
4.One diagonal and one angle.
