The graph as well as other important points are simply wrong: The time at 90° amplitude is 18% larger than T0 and not 7.3% as shown in the plot. Then, the author plots the integrand instead of the integral. Furthermore, he calculates sin(th0)/2 instead of sin(th0/2). Means, this page is seriously flawed! —Preceding unsigned comment added by Looser2 (talk • contribs) 16:38, April 3, 2007
