Wooho. | And I do | plenty of spherical geometry (GPS navigation) without requiring the sin | of 2**90. ;) Yeah, the problem with people who work only with angles is that they tend to forget that sin (and friends) are defined as functions on *numbers*, not just angles or whatever, and happen to appear in approximations of functions as series (e.g. Fourier series) and therefore those functions can be applied to things that are not just "angles". -- Gaby
