Thus we say that online free tutoring is a tool of internet, in which any child can use to get the solution to all the problems.

In order to find the Volume of a Prism, we can use online math tutor, which is available for free. We can download cbse board papers for different subjects which are used to guide the students for preparing for the exams of different grades.

free online math tutor

Posted on July 18, 2012. Filed under: Uncategorized | Tags: , , |

Free online math tutor is available online to learn about the different topics of mathematics. These tutors are available online by different companies, which a child can surf any day even in the odd hours when ever required. So we say that the  child can take the guidance of the difficult topics from the online math tutors which can support the students to open the desired topics and can clear the doubts and the problem to the related topics. Now we say that the understanding of the topics becomes easy and such lessons can be repeated played online without any hesitation of asking the problems time and again.

We must look at the desired topics and find the examples based on the topic. We have many worksheets and quiz available in the math tutors which can support us to understand the topics more clearly.

 Online math tutors are so well designed that it makes the topic quite interesting and it helps to clear the concepts and the doubts of the child who uses it.

Besides this a special expert team of the  teachers is appointed by the software companies which develop the lesson plans for the  particular tutor website. Different online tutor companies are available through out the world which can help the students to excel in their examination through their proper guidance and the lessons available online. 


Even the special queries related to any particular topic and subjects can be solved by the online tutor and the child can clarify his math problems by the online tutorials when ever he finds himself held up anywhere.

We can learn about the  Volume of Rectangular Prism by the help of  logging in to math online tutorials. The cbse syllabus 2013, for different subjects are also available online which can help the students to know the topics in the syllabus of the given topics.

How to Tackle Linear Regression Problems

Posted on July 10, 2012. Filed under: Uncategorized | Tags: , , |

The term linear regression is commonly used in the theory of the statistics. It can be defined as an approach towards the modeling of the relationship between any scalar variable say y which is dependent and 1 or more variables which are explanatory represented by X. When we have only 1 variable which is explanatory then it is known as the simple regression. And when we have greater than 1 variable which is explanatory then it is known as the multiple regression.

However the multiple type of the regression should not be confused with the multivariate type of the linear regression in which correlated variables which are dependent are being predicted unlike just a single variable which is scalar. (know more about Linear regression , here)

Under the linear regression, the data is modeled with the help of the linear type predictor functions and the unknown type parameters of the model are judged by the data. These types of the models are known as the linear models. Generally linear type of the regression is being referred as a model where the conditional type mean of the y is called as an affine function of the X if the value of the X is given.

And in rare case this type of the regression is referred as a model where the median or any quantile of the conditional type of the distribution of the y is represented in the form of any linear function of the X if the value of the X is given. It should be known that it is the 1st kind of the regression that is being studied so rigorously and is being utilized in many practical uses.

Question like find the circumference of a circle is regularly asked in CBSE board papers. You can visit various online portals to get all informations regarding CBSE board papers and questions.

Define Equivalence Relation

Posted on July 5, 2012. Filed under: Uncategorized | Tags: , , |

Equivalence relation describe in mathematics and define as a relation that is reflexive , symmetric and transitive. We can define these properties of relation as if there is a relation R then it said to be equivalence relation that is based on a set A if relation on set A is reflexive means Set A have relation in itself that means A ÃÂ„ A .

If relation on set A is symmetric that means if set A have relation in set B then set S also have the same relation in set A that is describe as A ÃÂ„ B then B Є A.

And at last if there is a relation that is transitive means if set A have relation in set B and set B have relation in set C then A also have the relation in set C that is describe as A R B and B R C then A R C

for all the elements of set A , B and C.

we describe the equivalence relation by a simple example as

Chain Rule Calculus is used to find the derivative of the composition function that is two or more than two. Equivalence relation is defined by the symbol Ã¢ÂÂ“ . (Know more about Equivalence Relation in broad manner, here,)

If Set s = 1 , 2 , 3 and there is relation R that is equivalent on set s if relation R have all the subset that define all three properties that are reflexive , symmetric and transitive means

R = (1 , 1) ,(2 , 2) , (3 , 3) , (1 , 2) ,(2 ,1) , (1 , 3) , (3 , 1) , (2 , 3) , (3 , 2) , so relation R is called as equivalence relation.
