NAME
csin -- complex sine function
ccos -- complex cosine function
ctan -- complex tangent function
SYNOPSIS
#include <complex.h>

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 func-
tions 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.
