the area of the inscribed polygon for Case 1 is of the area of

But, by Case 1, the th of the area of the circumscribed polygon

Again, by Case 1, the sine is 5' the given polygon; and, by Case 2, each of these sines is divided into 14 parts, each equal to tangent No. 2; therefore there are 44 X 14=

616 tangents contained in the polygon for Case 1, each equal to

Consequently the sum of the sines for Case 3 is the same as the sum of the sines for Case 2.

By Case 3, the sine is

Therefore the sum of the sines for Case 3 is exactly the same as the sum of the sines for Case 4, and the length of the perimeter of the inscribed polygon is not changed.

Then, multiplying the sine by double the number of sides, we have 74226252905747712062

Thus we perceive that the sum of the sines, that is the perimeter of the inscribed polygon, from Case 1 to Case 5, inclusive, is constantly changing the number of its sides at a rate much more rapid than by doubling, while the length of the perimeter, as well as the radius, and

the area of the inscribed polygon constantly remains the same; and, if the number of sides were increased ad infinitum, they would still continue to be the same, although at every successive step the usual number of sides, according to hypothesis, has been deducted.

By Case 2, the tangent is ; and, by Case 3, the tangent is
