6.2.57 csin Function

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

Include

<complex.h>

Prototype

double complex csin(double complex z);

Argument

z

value for which to return the complex sine

Return Value

Returns the complex 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 = csin(x);
  printf("The complex sine of %f + %fi is %f + %fi\n", creal(x), cimag(x), creal(y), cimag(y));
}

Example Output

The complex sine of -2.000000 + 1.000000i is -1.403119 + -0.489056i
