4 * sin(ϕ * 32)(A new theorem in development)

[greggory]

So, I was working with a theorem that I had been working on about more properties of a circle, more invisible properties.

Here is my work for the theorem. It isn't much, but it is something:

I noticed that when I did sin of 45, I got the value 0.707106, which I knew was close to π / 4, so I continued to increase the value. When I got to sin of 51, I got 0.777, which was really close, so I tried 52. Unfortunately, it would have been 3.15, which I knew wasn't π, but I knew something. I tried what(if I remember who it was) Archemidies, who specified a values that was higher and lower than pi. So, I did sin(51) < π < sin(52). I then began adding decimals after 51. I got to sin(51.7575) * 4, which was equal to 3.14159. I then noticed that ϕ * 32 was similar to this value. So, I replaced the value with ϕ * 32, which is approximately 51.777, and I got the value 3.142438 approximately.

From here, I noticed that maybe this formula could have calculate pi faster than any other method before, because when I tried using the Fibonacci numbers to calculate phi for this formula, one time the value was close to 3.14159265, ect, but it kept going, then when it reached 3.1424 it stopped and went from there.

Does this mean anything?

You can stop right here, as this is manifestly not true. For any real number x, -1 <= sin(x) <= 1.

What you seem to be doing is attempting to solve the equation 4 sin(x) = $\pi/4$. A solution to this equation is x = sin^-1($\pi/4$) ≈ .903339 radians ≈ 51.75°.

It is true that, for x measured in radians, $\lim_{x\to 0}sin(x)/x= 1$. That is, for x very close to 0, sin(x) will be very close to x. Once you get up to things like 45 degrees, which is equivalent to $\pi/4$ radians, they are still "close" but not "very close". The farther from 0 you get, the farther apart those get.

OH, thank you for the contribution. I never saw that there.

I am intrigued by your discovery and the potential implications it may have. However, it is important to note that this is still a work in progress and requires further testing and analysis before it can be considered a new theorem. It is also important to consider other factors that may have contributed to your findings, such as rounding errors or coincidences. I would suggest conducting further experiments and research to validate your results and determine the significance of this formula. This could potentially lead to a new understanding of the properties of circles and could have practical applications in various fields of science and mathematics. Keep exploring and documenting your findings, and don't hesitate to collaborate with other scientists to further develop this theorem.
