CUMULATIVE DISTRIBUTION FUNCTION, Q(e;b) 



Fig. 7.1 — Cumulative distribution function for the angle. 



Thus, the fact that the curve for ^ = is a straight Hne, whose equation is 

 (3(0 ;0) = e/2-w = 07360°, {b = 0), 

 corresponds to the fact that for 6 = the equiprobability curves are circles.
