Improved trig help files.

Added new vercos(x, [,eps]) for versed cosine and covercos(x, [,eps])
for inverse versed cosine.

Added new avercos(x, [,eps]) for inverse versed cosine and acovercos(x, [,eps])
for inverse coversed cosine.

DESCRIPTION
Calculate the coversed sine of x to a multiple of eps with error less in
Calculate the coversed trigonometric sine of x to a multiple of eps with error less in
absolute value than .75 * eps.
The coversed sine function is sometimes called covers, or cosiv, or cvs,
may be defined as:
This function is sometimes called covers, or cvs, is equivalent to:
coversin(x) = 1 - sin(x)
