cosh function

Complex<num, num> cosh(
  1. Complex<num, num> complex
)

Return the hyperbolic cosine of complex.

Implementation

Complex<num, num> cosh(Complex complex) {
  var r = _cosh(complex.real) * math.cos(complex.imaginary);
  var i = _sinh(complex.imaginary) * math.sin(complex.imaginary);
  return Complex<num, num>(r, i);
}
