std::cosh(std::complex)

Header: <complex>

Computes complex hyperbolic cosine of a complex value z.

# Declarations

template< class T >
complex<T> cosh( const complex<T>& z );

(since C++11)

# Parameters

• z: complex value

# Return value

If no errors occur, complex hyperbolic cosine of z is returned.

# Notes

Hyperbolic cosine is an entire function in the complex plane and has no branch cuts. It is periodic with respect to the imaginary component, with period 2πi.
