Formulas of the hyperbolic cosine
In the following description, \(z\) stands for the complex number. \(x\) stands for the real value \(Re\) and \(y\) for the imaginary value \(Im\).
\(cosh(z) = cosh(x) · cos(y) - sinh(x) · sin(y)\)
Example
\(cosh(z) = cosh(3+5i)\)
\(Re = cosh(3) · cos(5) =2.856\) \(Im = sinh(3) · sin(5) =9.606\)
\(cosh(3+5i) = 2.846-9.606i\)
