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);

     long double complex
     ccosl(long double complex z);

     float complex
     ccosf(float complex z);

     double complex
     ctan(double complex z);

     long double complex
     ctanl(long double complex z);

     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).

SEE ALSO
     csinh(3) ccosh(3) ctanh(3) complex(3)

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