DESCRIPTION
sind(x), cosd(x), and tand(x) compute trigonometric functions of angles
measured in degrees: sind(x) := sin(x * pi/180), and similarly for
cosd(x) and tand(x).
sincosd(x, s, c) simultaneously sets *s = sind(x) and *c = cosd(x).
The corresponding inverse functions compute asind(x) := asin(x) *
180/pi, and similarly for acosd(x) and atand(x). Also, atan2d(y, x) :=
atan2(y, x) * 180/pi.
