result with little or no significance.

Synopsis

#include <math.h> 

double cos(double x);

float cosf(float x);

Returns

The cosine value.

Example

double y=.1234;

double x;

x=cos(y);

cosh, coshf

Computes the hyperbolic cosine of x. A range error occurs if the magnitude of x is too

large.

Synopsis

#include <math.h> 

double cosh(double x);

float coshf(float x);

Returns

The hyperbolic cosine value.

Example

double y=.1234;

double x

x=cosh(y);

div

Computes the quotient and remainder of the division of the numerator numer by the

denominator
