NAME
    csc - trigonometric cosecant function

SYNOPSIS
    csc(x [,eps])

TYPES
    x		real
    eps		nonzero real, defaults to epsilon()

    return	real

DESCRIPTION
    Calculate the cosecant of x to a multiple of eps, with error less
    in absolute value than .75 * eps.

EXAMPLE
    > print csc(1, 1e-5), csc(1, 1e-10), csc(1, 1e-15), csc(1, 1e-20)
    1.1884 1.1883951058 1.188395105778121 1.18839510577812121626

LIMITS
    unlike sin and cos, x must be real
    eps > 0

LIBRARY
    NUMBER *qcsc(NUMBER *x, NUMBER *eps)
