std::sin(std::complex) - cppreference.com (original) (raw)
| | | | | ------------------------------------------------------------- | | | | template< class T > complex<T> sin( const complex<T>& z ); | | |
Computes complex sine of a complex value z.
[edit] Parameters
[edit] Return value
If no errors occur, the complex sine of z is returned.
Errors and special cases are handled as if the operation is implemented by -i * std::sinh(i * z), where i is the imaginary unit.
[edit] Notes
The sine is an entire function on the complex plane, and has no branch cuts.
Mathematical definition of the sine is sin z = .
[edit] Example
Output:
sin(1.000000,0.000000) = (0.841471,0.000000) ( sin(1) = 0.841471) sin(0.000000,1.000000) = (0.000000,1.175201) (sinh(1) = 1.175201)
