ewmon Posted July 14, 2013 Share Posted July 14, 2013 I got to thinking about this from two recent threads on the nature of pi. We're all familiar with scribing a semi-circle using two points (A and C) and a right triangle, shown below. How then would the distance along the circumference of the semi-circle be computed using integration? Can it be done without using trigonometry, or is trig inherently part of the process? Pi would then be the ratio of the semi-circle's circumference to ½ of AC. I apologize for not thinking this out myself, but I haven't focused in this mathematical direction in quite some time.
