```CCOS(3) 						   BSD Library Functions Manual 						   CCOS(3)

NAME
ccos, ccosf, csin, csinf ctan, ctanf -- complex trigonometric functions

LIBRARY
Math Library (libm, -lm)

SYNOPSIS
#include <complex.h>

double complex
ccos(double complex z);

float complex
ccosf(float complex z);

double complex
csin(double complex z);

float complex
csinf(float complex z);

double complex
ctan(double complex z);

float complex
ctanf(float complex z);

DESCRIPTION
The ccos(), csin(), and ctan() functions compute the cosine, sine, and tangent of the complex number z, respectively.  The ccosf(), csinf(),
and ctanf() functions perform the same operations in float precision.

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).

csinh(3) ccosh(3) ctanh(3) complex(3)

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

The Whole Story on #! /usr/bin/ksh

Introduction Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it...

Unix File Permissions

Introduction I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls: \$ ls -ld /usr/bin /usr/bin/cat drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin -r-xr-xr-x 1 bin bin ...

Memory Leaks

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram. main() { malloc(1gb) return(0) } The program above exits without freeing the memory. In this case will the 1 gb of heap memory be returned...

Scripts without shebang

I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning . Does this mean that it will run on any shell ? Is it a good practice to create scripts (even ad-hoc ones) without shebang ?
