1. Introduction

We know that history of mathematics and education of mathematics both is two branch of mathematics science. A lot of Research scholar in word working and doing reasearch in this two branch of mathematics. Question is here that can these two group of researcher can help each other? Reality is that I n society of mathematics two idea are there on group which had idea that history of mathematics can help teacher of mathematics a lot and in next section we give some example to prove this idea in other group people have idea that history of mathematics can not help education of mathematics and we give some point of their view. In the end in comparison of this idea I give my conclusion.

2. On Application of History of Mathematics in Education of Mathematics

What is application of history of mathematics? We know that researcher duty in history of mathematics is to read mathematical manuscript, understand those things and rewrite them in new mathematics so which this work need expert people which know old language and mathematics and some idea about society of that time. For that reason society of historian of mathematics in every where is small in number (compare to other branches of mathematics). And from this small society few people teach mathematics or thinking about education of mathematics now usually %25 of papres in international conference of education of mathematics are about history of mathematics or its application [ ].

So joint work of historian of mathematics and education of mathematics can prepare material for teacher of mathematics and in higschools and. Universities. So when teacher came to know that time is suitable they can explain about history of geometry, algebra, analysis, graph theory, and so on spicily when students feel tired in classes and still we have time to end of classes. By explain of history of number student not only dose not feel tired but also waiting for next classes to know more about numbers.

Students by knowing life history of, paytogorian, Tales, Aryabahtyia, Ramurajan, Kharasmi, Kashani, Taragellia, …..

Will come to know that science is works of all civilization so they have respect for other nation young people of each civilization by history of mathematics will come to know that his old generation also had contribution on construction of science so they will find confidence.

One of goal of education of mathematics is to teach better and better. in the mathematical manuscripts we can find methods on mathematical operation s which if we teach in this manner student can do faster and understand better two example are as follow :

a) Doing multipication by Kashani method

Sutdent with Kashani method are more comfortable ^[4].

For better understanding of solving equations Islamic mathematicians use visualization for example Kharazmi use geometry to explanation of procedure. He wants to solve . He explain the system of solving in this manner: ^[2]

"Let the side of square ABCD is answer of equation. In direction ofAB and BC we choose since . The points E,F is middle of . Then me make square GFIH on GF so we have :

1)

So

if we can calculate area of this square on basis of b,c with squaring we have value of x from figure it is clear that

2)

From other side

3)

From 2 and 3

4)

5)

6)

From 3,4,5,6 we have

7)

From 1 and 7 we have :

Another application of history of mathematics is using correct name for correct formula in the below you can see a list of formula which named nucorrct.

and so on. ^[1]and ^[3].

In history of mathematics we have a lot of problem in different level which can improve mathematical thinking of student consider to following example: Example –1- Abolvafa Bozjani one of the famous mathematician of 328 of Hejry (940. A.D) he had very nice books which all translated in English and French. In his book with the name geometry operation there is very beautiful problem can make student interest and better thinking as follow:

“How we can make with three equal square a new square”

Let the student thinks for few minutes and compare their work with Bozjani method

Solution: Let a,b,c three equal square we divide two of them into two parts by diameter as follow:

3. Now the Mathematicians who are not Agreeing with History of Mathematics Claim that

Mathematical text for usage of teachers are not enough and if some history of mathematics book is there they do not know how to use them. Some problem in history of mathematics makes confusion for student like squaring the circle:

4. Squaring Circle by Ramrajan Method

Squaring the circle is another problem which different civilization was interested

It is seems very simple according to idea of students but when they start to calculate they will see it is not possible because

Area of a circle with diameter 1 is equal to

Since is unknown never we can find x. But different mathematician from different civilization tried to find a system to solve this problem ^[1].

In comparison of these wives we can conclude that positive points for co-existence of history of mathematics and education of mathematics are so much than negative point I will suggest that all those studying mathematics to be teacher must pass a course on history of mathematics.
