From point C draw two straight lines. ( the angle between them is 1 degree) Between the lines there is arc A. ( radius of arc 100 m) Tangent B appears at the midpoint of A The formulas for calculating A and B do not take into account , the actual radius length ( 100 m or 0.00001 m ) According to these formulas , always B > A According to the description i presented , it is possible that A > B

Since a tangent to a circle is always outside the circle, except at the point of tangency, the distance from C to B is always greater than the distance from C to A, except at the point of tangency. In that sense . I suggest that you take a good course in basic geometry before posting any more of these. I say that assuming you are neither a fool nor a troll.

I present a picture. Polygon of 360 ribs, with circle in it. a is the circumference of the circle. b is the circumference of the polygon. The formulas say , b > a and i say , there is a condition , a > b Details in the article. http://img2.timg.co.il/forums/2/2357...506e265a07.pdf

The OP is just silly. He is talking about measurement errors. He doesn't seem to realize that there is a perfectly good mathematical theory of errors. In my opinion, mathematical terminology is imbued with and weakened by Platonist metaphysics. No "irrational" number has ever been measured and recorded exactly. In other words, there is no physical evidence for the existence of the set of "real" numbers. So what? But mathematical objects are frequently idealizations of physical objects. If we called real numbers "ideal" numbers a lot of nonsense would be avoided. Of course that is not going to happen. There is too much intellectual capital tied up in the term "real number." So people with a distaste for metaphysics, or at least a distaste for Platonism, just recognize that pi relates to the perfect circles of the human imagination, not to constructions in a lab. What relates to constructions in a lab is a range of rational approximations to pi. Whether or not we are Platonists, most of us understand why physical measurement errors are irrelevant to pure mathematics by late adolescence.

You cannot prove anything in Mathematics by experiment. I would think that the nearest you can get would be to show or demonstrate that 5  3 = 2 by having 5 counters and taking 3 away. but demonstrating one example is not proof in the mathematical sense.

The mathematicians decided that a circle is a mathematical subject. But this is not true, a circle is a physical issue. Thus, for 2,000 years, mathematicians have not discovered the idea of changing pi Mathematicians will not agree with what I say here thanks

The mathematics is discrete and discontinuous. The geometric line is continuous, and mathematics can not handle it. Thus, mathematics has not discovered the idea of variable pie, for 2000 years. Thanks
