The further importance of that is............2 ^i...........using i as an exponent for 2...............is the square root of 8 or the square root of 10.....................e and pi respectively..............fair approx. for both................adding under the radicand............that is 18.........imp b/c......matching beg to end.............for the 1st 25 primes.........2, 3.............and 89, 97...................2 twos...................the gap between the two beg primes.......is 1.............the last two is 8......................18........taken together.........adding the two 9's.........from 89, 97........9 + 9 = 18.........two 18's...........on diff. levels of meaning............18 + 18 = 36........full circle..........pi is 180 degrees.......on the unit circle..........



function is fairly flat, but with a large number of horizontal ridges. It is precisely along these ridges that the nontrivial zeros of lie.
The position of the complex zeros can be seen slightly more easily by plotting the contours of zero real (red) and imaginary (blue) parts, as illustrated above. The zeros (indicated as black dots) occur where the curves intersect.
