DESCRIPTION
Returns the cosh of x to a multiple of eps with error less in
Returns the acosh of x to a multiple of eps with error less in
absolute value than .75 * eps.
acosh(x) = ln(x + sqrt(x^2 - 1)) is the nonnegative real number v
for which cosh(v) = x.
acosh(x) is the nonnegative real number v for which cosh(v) = x.
It is given by
acosh(x) = ln(x + sqrt(x^2 - 1))
EXAMPLE
> print acosh(2, 1e-5), acosh(2, 1e-10), acosh(2, 1e-15), acosh(2, 1e-20)
