CSIN(3)

NAME
csin - complex sine function
ccos - complex cosine function
ctan - complex tangent function

SYNOPSIS
#include <complex.h>
double complex
csin(double complex z);
long double complex
csinl(long double complex z);
float complex
csinf(float complex z);
double complex
ccos(double complex z);

double complex
ctan(double complex z);
long double complex

float complex
ctanf(float complex z);

DESCRIPTION
csin(z) computes the sine of the complex floating-point number z.

ccos(z) computes the cosine of the complex floating-point number z.

ctan(z) computes the tangent of the complex floating-point number z.

NOTES
csin, ccos, and ctan are defined in terms of the complex hyperbolic functions as follows:

    csin(z) = -i * csinh(i*z),
    ccos(z) = ccosh(i*z),
    ctan(z) = -i * ctanh(i*z).

STANDARDS
The csin(), ccos(), and ctan() functions conform to ISO/IEC 9899:2011.
