sin, sinh

Visual Studio 6.0

Calculate sines and hyperbolic sines.

double sin( double x );

double sinh( double x );

Routine Required Header Compatibility
sin <math.h> ANSI, Win 95, Win NT
sinh <math.h> ANSI, Win 95, Win NT

For additional compatibility information, see Compatibility in the Introduction.

Libraries

LIBC.LIB Single thread static library, retail version
LIBCMT.LIB Multithread static library, retail version
MSVCRT.LIB Import library for MSVCRT.DLL, retail version

Return Value

sin returns the sine of x. If x is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result occurs, in which case the function generates a _TLOSS error and returns an indefinite (same as a quiet NaN).

sinh returns the hyperbolic sine of x. If the result is too large, sinh sets errno to ERANGE and returns ±HUGE_VAL. You can modify error handling with _matherr.

Parameter

x

Angle in radians

Example

/* SINCOS.C: This program displays the sine, hyperbolic
 * sine, cosine, and hyperbolic cosine of pi / 2.
 */

#include <math.h>
#include <stdio.h>

void main( void )
{
   double pi = 3.1415926535;
   double x, y;

   x = pi / 2;
   y = sin( x );
   printf( "sin( %f ) = %f\n", x, y );
   y = sinh( x );
   printf( "sinh( %f ) = %f\n",x, y );
   y = cos( x );
   printf( "cos( %f ) = %f\n", x, y );
   y = cosh( x );
   printf( "cosh( %f ) = %f\n",x, y );
}

Output

sin( 1.570796 ) = 1.000000
sinh( 1.570796 ) = 2.301299
cos( 1.570796 ) = 0.000000
cosh( 1.570796 ) = 2.509178
