OK boys, this one has been a wonderment to me for years.
They tell me that the ancient Greeks came up with the formula for the sine tables. Now, since these constants are expressed in numbers carried out to 7 or 8 decimal places, how did these old boys figure that shit out in the first place? How did they come up with Pi?
They didn't have all the stuff to take measurements that we do today. So my question is, is there some sort of natural law that they were able to apply to get the sines, cosines, tangents, etc?
