NAME

6       csin, csinf, csinl - complex sine function
7

LIBRARY

9       Math library (libm, -lm)
10

SYNOPSIS

12       #include <complex.h>
13
14       double complex csin(double complex z);
15       float complex csinf(float complex z);
16       long double complex csinl(long double complex z);
17

DESCRIPTION

19       These functions calculate the complex sine of z.
20
21       The complex sine function is defined as:
22
23           csin(z) = (exp(i * z) - exp(-i * z)) / (2 * i)
