 The Institute of Reproducing Kernels is dealing with the theory of division by zero calculus and declares that the division by zero was discovered as $0/0=1/0=z/0=0$ in a natural sense on 2014.2.2. The result shows a new basic idea on the universe and space based on the new concept of division by zero calculus: for the function $f(z) = 1/z$

$$

f(0) = 0

$$

 since Aristotelēs (BC384 - BC322) and Euclid (BC 3 Century - ), and the division by zero is since Brahmagupta  (598 - 668 ?).

In particular,  Brahmagupta defined as $0/0=0$ in Brāhmasphuṭasiddhānta (628), however, our world history stated that his definition $0/0=0$ is wrong over 1300 years, but, we showed that his definition is suitable.

we will present our results while 11:00-12:00, October 23 and we will accept all the related questions and comments while 13:00-15:00 around.

For the details, please see the below:

\medskip

(If a person participates in our session around the morning and afternoon free discussions, he should pay euro 250. If the person registers in a group of 5 or more, the amount will be reduced to euro 180 per person. The morning session is very valuable and has the potential to bring change in the education system.

For one night stay on 22nd October, he needs to pay euro 150.

I hope everything is clear.

Kindly let me know if any query.

Thanks!

Regards,

John)

{\Huge \bf

Close the mysterious and long history of division by zero and \\ open the new world since Aristoteles-Euclid:　$1/0=0/0=z/0= \tan (\pi/2)=0.$

{\large \bf

For a triangle ABC with side length $a,b,c$.

We have the formula

$$

\frac{a^2 + b^2 - c^2}{a^2 - b^2 + c^2} = \frac{\tan B}{\tan C}.

$$

If $ a^2 + b^2 - c^2 =0$, then $C = \pi/2$. Then,

$$

0 =  \frac{\tan B}{\tan \frac{\pi}{2}} = \frac{\tan B}{0}.

$$

Meanwhile, for the case

$

a^2 - b^2 + c^2 =0,

$

then $B = \pi/2$, and we have

$$

\frac{a^2 + b^2 - c^2}{0}= \frac{\tan \frac{\pi}{2}}{\tan C}=0.

$$
