### Number Relation in table 9 for Primary Students

In mathematics, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic system.

Visual representation of the different multiplication tables from 2 to 50 The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations with base-ten numbers. Many educators believe it is necessary to memorize the table up 9 multiply by 9.

### Inverse Functions

Let the function   y=f(x)  be defined as the set of   X
and have a range  Y.

If the each   y   is the element of   Y  there exists a single value of   x   such that    f(x)=y.

then this correspondence defines a certain function  x=g(y)
called inverse with respect to given function   y=f(x).

The sufficient condition for existence of an inverse is  a strict monotony of the original function
y=f(x).

If the function increases (decreases), then the inverse function is also decreases (increases).

Graph of the inverse function   x=g(y)  coincides with that of the function   y=f(x)   if the independent variable is marked off along the    y-axis.   If the independent variable is laid off along the   x-axis   i.e. if the inverse function is written in the form    y=g(x),     then the graph of the inverse function will be symmetric to that of the function     y=f(x)    with respect to the bisector of the first and third quadrant.

### Project About "How to become Global Citizen"

Ed News

Open Project for
All

We are happy
to inform you that we have started a great project for students of
entire world.  We have started a project in which students
have to share their idea about “How we become a Global Citizen”
people.  Actually we know that in today’s world the boundaries
of nation are not meant like ancient world. We have Internet and
many other Communication Medias to communicate and make contact
with the people of other parts of this world. The people of this
modern world always are in touch with each other.  We know
that the students are more social in these days with their
international friends and partners. In these days teachers and
students are using internet for their teaching and study purpose.
It does not mean that the teachers and students are from which
nation. It is my request to students and teachers that please take
part in this project which is organized by “Join Study”. To join
this project please fill the following form and send us. Then we
wil…

### A Discussion about a Simple Problem Integral_0^pi cot(x) dx

This is very simple problem but as per request of my student now i am starting a discussion about it.
Now see
This Integral does not converge.
Visual representation of the integral:
Nonintegrable singularities of the integrand in the integration interval:

If you have any thought for this discussion please post in the place of comments.
