cos, cosh (Windows CE 5.0)
Developing an Application > Microsoft C Run-time Library for Windows CE > Run-time Library Reference
Calculate the cosine (cos) or hyperbolic cosine (cosh).
double cos( double x
);double cosh( double x
);
Parameters
- x
Angle in radians.
Return Values
The cos and cosh functions return the cosine and hyperbolic cosine, respectively, 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 of a call to cos occurs, in which case the function generates a _TLOSS error and returns an indefinite (same as a quiet NaN).
If the result is too large in a cosh call, the function returns HUGE_VAL.
Example
/* SINCOS.C: This program displays the sine, hyperbolic
* sine, cosine, and hyperbolic cosine of pi / 2.
*/
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
