SIN COS and TAN (Function)

,, and   are system functions which take one parameter (an angle, in units of radians), and give, respectively, the sine, cosine, and tangent of that angle. appears to be the least accurate of these three functions; it is better to stick to using  and   if possible.

If -0 is used as a parameter to any of the trigonometric functions, the system will stop responding (crash).
