NAME
sin - trigonometric sine
SYNOPSIS
sin(x [,eps])
TYPES
x number (real or complex)
eps nonzero real, defaults to epsilon()
return number
DESCRIPTION
Calculate the sine of x to a multiple of eps with error less in
absolute value than .75 * eps.
EXAMPLE
> print sin(1, 1e-5), sin(1, 1e-10), sin(1, 1e-15), sin(1, 1e-20)
