sinh method
Hyperbolic sine
Compute the hyperbolic sine of this complex number.
Implements the formula:
sinh(a + bi) = sinh(a)cos(b)) + cosh(a)sin(b)i
where the (real) functions on the right-hand side are math.sin, math.cos, fastmath.cosh and fastmath.sinh.
Returns nan
if either real or imaginary part of the
input argument is NaN
.
Infinite values in real or imaginary parts of the input may result in infinite or NaN values returned in parts of the result.
Examples:
sinh(1 ± INFINITY i) = NaN + NaN i
sinh(±INFINITY + i) = ± INFINITY + INFINITY i
sinh(±INFINITY ± INFINITY i) = NaN + NaN i
Implementation
Complex sinh() {
if (isNaN) return Complex.nan;
final _real = fastmath.sinh(real) * math.cos(imaginary);
final _imag = fastmath.cosh(real) * math.sin(imaginary);
return Cartesian(_real, _imag);
}
