Then OJ trisects the given angle.
The spherical A isosceles triangles AJB, BJC are con gruent, and we see that AB can be brought into the position BC by a rotation about the axis OJ through an FIG.
The axis of resultant angular momentum is therefore normal to the tangent plane at J, and does not coincide with OJ unless the latter be a principal axis.
Then with centre 0 1 and radius OJ, =OA 1, describe an arc. By reflecting the two arcs thus described over the centre the ellipse is approximately described.
For something a little out of the ordinary, an OJ Flower Bikini with full top is daring, but adorable, while a Wacky Waikiki bikini with pull-on skirt allows you extra coverage if you want to hit the shops after swimming.
