csin, csinf, csinl − complex sine function
Math library (libm, −lm)
#include <complex.h>
double
complex csin(double complex z);
float complex csinf(float complex z);
long double complex csinl(long double complex
z);
These functions calculate the complex sine of z.
The complex sine function is defined as:
csin(z) = (exp(i * z) − exp(−i * z)) / (2 * i)
