What will be  when ( Pi/infinity)*infinity ? 

From usual definitions it would be \(\pi/\infty = 0\) and \(0 \cdot \infty = 0,\) so that means \((\pi/\infty)\cdot \infty = 0.\) But it seems you are trying to treat \(\infty\) as if it were a natural number, and that has only small chance or working out. I do not think that you need to introduce \(\infty\) in the first place anyway.

Let's consider that stupid rule instead of true science because it will appear again and again . 

(Pi/million)*million=Pi

(Pi/billion)*billion=Pi

There is no trend to reduce result therefore so called scientists should prove that billion is not nearer to infinity than million.

Yes. Let's consider next thing:

Arc Pi -2 a   is divided for infinite quantity equal parts  and its chord is divided for infinite quantity of equal parts.The straight line intersects the nearest points of the divisions to its middle . The point on arc has coordinates([Pi-2a]/infinity ; 1), the point on chord has coordinates (cos(a)/infinity ; sin(a)). Their straight line intersects y axis in point(0; y1) . Increased side (Pi - 2a)/infinity of the triangle in infinite quantity of times on tangent in point(0 ; 1) creates new point on its edge with coordinates ([Pi - 2a] ; 1). Increased side cos(a)/infinity of the smaller triangle in infinite quantity times has edge point(cos(a) ; sin(a)). The new straight line of the new points intersects y axis in the same point (0 ; y1).

y1 = (2a - Pi*sin2(a)) / (2a*sin(a) - Pi*sin(a)+2a*cos(a))

Some similar thing we can make with edge points of the division. Then their derivative points lie on straight line which intersects y axis in point(0 ; y2) I did not make equation for y2.

But feature exists there :         y1 is lower than y2  when arc is bigger than Pi - 2a

                                     and         y1 is upper than y2  when arc is smaller than Pi - 2a

It can prove that the arc of definition of trigonometric functions exists.

I mistaken there

    y1=[sin(a)*(Pi - 2a) - 2cos(a)] / [Pi-2cos(a)-2a]

     y2= [2sin(a)*cos(a)+2a - Pi ] / [2cos(a) - sin(a)*(Pi - 2a)]

Now everyone can define is any arc less or more than the arc of definition.

I have got  such complex equation

                                                      a=

((31/2 - 21/2)cos(a)+(2*21/2 - 3)sin(a)+(3*21/2 -2*61/2)/2))*Pi / ((4*21/2 - 6)sin(a) - 2*61/2+3*21/2)=

={4Pi - 4cos(a) + 4sin(a)cos(a) - 4Pi*sin2(a) - [(4cos(a) - 4Pi - 4sin(a)cos(a)+4Pi*sin2(a))2 - (16 - 16sin2(a))*(Pi2 - 2Pi*cos(a)+4sin(a)cos2(a) - Pi2sin2(a)+2Pi*sin(a)cos(a))]1/2} / {8-8sin2(a)}

Theoretically it can be solved, then sin(a) , cos(a)  and a will be known. Then we can not only exactly define trigonometric functions  but and write them down as numbers. Ofcourse we can describe trigonometric functions which relate to Pi  by nambers with exponents and mathematical actions only relative to Pi. But it maybe usefule for solve of Travelling salesman problem.

The idea is wrong because next formula must work but it is not working

t/(1-y)=sin t/(cos t -y)

y=(t cost-sint)/(t-sint)

Rather that is wrong because t is not obligated to be proportional to ( Pi-2a)/2 at level 1.

No. [tex]0*\infty[/tex] is NOT 0, it is "undefined". [tex]\frac{\pi}{\infty}*\infty[/tex] is "undefined".
