 OFFSET 0,1 COMMENTS Solution to the three dimensional version of Mrs. Miniver's problem. The intersection volume is equal to 2/3 of the volume of each sphere, i.e., 8*Pi/9. LINKS Eric Weisstein's World of Mathematics, Sphere-Sphere Intersection. Wikipedia, Mrs. Miniver's problem. FORMULA Equals 4 * sin(arccos(-1/3)/3 - Pi/6). The smaller of the two positive roots of the equation x^3 - 12*x + 16/3 = 0. EXAMPLE 0.452147427578415981828610831183181263247509153259677...
