I can't believe that this thread has gone on for 50 posts. Obviously Kadomole came up with an equation that matched what he thought was "". He simply does not know what "" is. If he is, say, 12 or 13 years old, I would commend him for his (misguided) attempts. If he is older than that, it is really very sad.

We are now on post 51, and we still do not have his putative "proof." I strongly suspect that we never shall be given a look at that "proof."

Newbie Joined: Jan 2017 From: mwanza tanzania Posts: 20 Thanks: 0  You are right; now use these HINTS: {area of triangle=0.5r^2[4+[pi^2]/4]sinx=pi[r^2], sinx={8pi}/[16+[pi]^2}, draw a rightangled triangle with angle x, opposite side = 8pi, hypotenuse side = 16+pi^2, and adjacent side = plus[+] or minus [] sqrt[[16+pi^2]]^2  64pi^2, obtain value of tanx from that triangle, use tanx=[2tanx/2]/[1[tanx/2]^2], use tanx/2 = pi/4, finish on calculating value of pi. Test your pi value by drawing a rightangled triangle with sides sqrt8, sqrt8 and 4, one angle = pi/4, calculate different trigonometric ratio like sin[pi]/2, tan[pi]/4, sin[pi/4], etc. What do you comment on pi value? kadomole

I have chosen to intervene. I ask all other members to refrain from further discussion until the issues addressed below are resolved. Quote:
As previously asked, how is this equation used to determine the value of $\pi$ (pi)? Note that $\pi\ne3.1425...$ Please respond explicitly. Do not refer to previous posts without directly quoting them. Include all relevant details. Failure to do so will result in this thread being closed.
