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)
    .84147 .8414709848 .841470984807896 .84147098480789650665

    > print sin(2 + 3i, 1e-5), sin(2 + 3i, 1e-10)
    9.1545-4.16891i 9.1544991469-4.16890696i

    > pi = pi(1e-20)
    > print sin(pi/6, 1e-10), sin(pi/2, 1e-10), sin(pi, 1e-10)
    .5 1 0

LIMITS
    eps > 0
