The Speciality of 0.7071068 & 0.2928932 within 45 degrees 👇

Arclength = (X/45) - (X/45)*Sin45 + (X/45)*(Sin45)^2

Mindblowingly, it's similar with 👇

Arclength = (X/45) - (X/45)*(1-Cos45) + (X/45)*(1-Cos45)^2

Cylinder & Tape Experiment

1. Measure the circumference.
2. Figure out the pi's claim for the diameter.
3. Measure the diameter based on pi's claim IOW stick the ruler's number as claimed by pi, on the right side of the diameter's edge.
4. You'll get dizzy :o ;D

the problem is: trigonometry is not fully trustworthy.
Why not?
Care to provide an example where it is wrong?

Arclength = (X/45) - (X/45)*Sin45 + (X/45)*(Sin45)^2
And what is x meant to be here?
How does that relate to arc length?


Mindblowingly, it's similar with
It isn't mindblowing at all.
Factoring out the (X/45) (and ignoring it), the top is:
BS = 1-sin(45)+sin(45)^2.
The bottom is:
BS=1-(1-cos(45))+(1-cos(45))^2
Expanded that is:
BS=1-1+cos(45)+1-2*cos(45)+cos(45)^2
Simplified that is:
BS=1-cos(45)+cos(45)^2

i.e. all you are saying is that:
sin(45)=cos(45).
And that isn't surprising at all.

"So now you're admitting pi is correct?"

>> Changing idea is a usual thing. I might return to phew next time if I find new findings.

the problem is: trigonometry is not fully trustworthy.
Show one example where trigonometry is wrong....just one.

Okay, you tolerate the very-very close trigonometrical values of pi to the real value..

Fine...


You cannot figure out the true value of pi, but you use it in daily usage coz the approximated value is super close to the supposed value...

Fine...

As I said before, pi is right by maths.

On the other hands, there is something tempting >> phew gives 'mind blowing maths geometry'...

If you dump it, it's fine, but me would not. I'm still researching phew, even if it's not correct. Its special geometry must have something special to reveal.

At least for the time being I'd say:

Maybe phew is not applicable for maths, but it's worth to be put in other fields.

Example:

What if, you live in an era before Archimedes when people had no idea about the true C/D?

And then phew came up with "mindbliwing maths and geometry".

If people easily accepted phew, that means they were already deceived by their eyes. In this case they didn't go into details as well as real calculations, on the other hand, they just believed phew by taking for granted due to its 'mindblowing' maths and geometry.

How about now, or in the near future?

Are people being blinded by what they see just because they are carried away by 'glitters' which are in fact false?

Glitters can be everything: Celebrities, 'evidences', religious leaders, etc.

What if, Antichrist- the king of lies- is coming in the near future??

or, I should also say:

What if Antichrist actually has come to the world for such a long time?? :o

Are most people able to endure against Antichrist's 'miracles' which are actually false?? :o

The real value can never be figured out exactly as it is an irrational number.

Instead an approximation is used which is of a level of precision required for the task.

As I said before, pi is right by maths.
And that is what is important.
You liking something better for nonsense reasons doesn't make it better or correct, nor does it make pi wrong.

There is nothing special about your phew BS.

What if, you live in an era before Archimedes when people had no idea about the true C/D?
And then phew came up with "mindbliwing maths and geometry".
If people easily accepted phew
Or in the more likely case that people just rejected it as unsubstantiated nonsense, you would be no better off.

The only benefit you would have is the lack of precision tools which could be used to show you are wrong.

Actually, in calculations the number of digits we use in pi is almost always more significant digits than the other terms in the equation.  The calculated result can't have more significant digits than the smallest term in the equation.  Even if pi had on 10 digits past the decimal it would still be more than necessary.  IOW, having more decimal places doesn't make the result more accurate.  Heck, 3.17157 is more significant digits that most equations would need.  It really doesn't matter how far out pi goes because 3.14159 is more than enough.

Not to mention there are many irrational numbers out there.  e.g. a right triangle with two legs of length 1 has a hypotenuse is √(2)...an irrational number.
As I said before, pi is right by maths.

 On the other hands, there is something tempting >> phew gives 'mind blowing maths geometry'...
'mind blowing maths geometry'...really?  It’s geometry.  The math either works or it doesn’t.  Don’t get me wrong.  Math is what I do for a living and some of it really cool but phew isn’t somehow going to make it party time.  There's nothing mind blowing about.

Pi only has analytical applications.  It doesn’t really do anything else.  So, I’m not really sure what “ glitters” or the “Antichrist” has do with the area of a circle or designing a mechanical watch.  I have absolutely no clue what this last bit has to do with...well anything.

I don't limit science fields.

Do you think phew will be useless forever?

To answer it, I still will research about it. Who knows there will be findings either outside maths and physics, or even inside maths and physics 8)

The mindblowing phew maths is the reason why I continue the research.

You deny the mindblowingness of phew maths? :o
I still don't get it why.

Yes.
It is incorrect and has no use.

You made it to try and combat pi, with absolutely no basis for it.

It has already been explained why.
There is nothing mindblowing about it. It is based entirely upon false pretenses, or just extremely simple things.

Perhaps you can try to explain why you think it is so mindblowing?

Nothing you have posted has been mindblowing.

Providing a number based upon other numbers isn't mindblowing.
You require your claims to be true to be mindblowing. But the fact that they are false makes them not-mindblowing and just simply stating that some collection of numbers when manipulated in a certain way equals another number.

If you wish to disagree, why not post one simple clear example of some allegedly mindblowing thing about phew?

I still don't understand what is so mind blowing about it.  Phew doesn't work.  It can't be measured, it can't be calculated, so what is mindblowing about it.  I've never understood that comment.

So you've "never understood that comment"! That's easy ;D.

"The mindblowingness of phew maths" has blown Danang's mind :o long ago and he hasn't had logical thought since.

Just look at any of his topics and you'll see the truth of that.
