.\" @(#)sin.3 4.1 (Berkeley) %G%
sin, cos, tan, asin, acos, atan, atan2 \- trigonometric functions
return trigonometric functions of radian arguments.
The magnitude of the argument should be checked
by the caller to make sure the result is meaningful.
returns the arc sin in the range \-\(*p/2 to \(*p/2.
returns the arc cosine in the range
returns the arc tangent of
in the range \-\(*p/2 to \(*p/2.
returns the arc tangent of
in the range \-\(*p to \(*p.
Arguments of magnitude greater than 1
at its singular points is a huge number, and
for arguments greater than about 2**31 is garbage.
