6.2.60 csinh Function

Calculates the complex hyperbolic sine function of a double precision complex value.

Include

<complex.h>

Prototype

double complex csinh(double complex z);

Argument

z

value for which to return the complex hyperbolic sine

Return Value

Returns the complex hyperbolic sine of z.

Example

See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <stdio.h>
#include <complex.h>

int main(void)
{
  double complex x, y;

  x = -2.0 + 1.0*I;
  y = csinh(x);
  printf("The complex hyperbolic sine of %f + %fi is %f + %fi\n", creal(x), cimag(x), creal(y), cimag(y));
}

Example Output

The complex hyperbolic sine of -2.000000 + 1.000000i is -1.959601 + 3.165779i
