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.

I have an SGI Octane. Can I run Windows XP Pro on it?I would like to use SolidWorks and Catia V5, as well as regular productivity software, on this hardware. I have been told that It is very good for design work. Though it is dated it apparently still has some use out of it. I am just trying to... (0 Replies)

Hi, this is my first post here.
I wanto make a screencasting program. I want to make a screen part selection to grab coordinates of the screen location.
I found a nice prototype
