Sine function in C programming Language
In this tutorial, we will discuss Sine function in C programming Language
Sine function in C
Description
Description of the C programming Language Sin() function
In C programming language the sine function returns the sine of the radian angle x.
sin(): In the C programming Language this is used to calculate sine value to given radians.
Declaration
The Declaration of the sin() function
double sin(double x);
Parameter or Arguments
the parameter of the sine function is:
x – This is the floating point value of an angle and always measured in radians(not degrees).
Returns
The sin() returns the sine of x, measured in radians.
Required header
In the C language, the required header of the sin() function in C
#include <math.h>
Example – Sin() in C programming
The following example shows the usage of sin() function
Program for Sine function in C
Program 1
#include <stdio.h>
#include <math.h>
int main()
{
double x=0.5,y=1;//define and initiates variables
printf("sine value of %f is %f\n",x,sin(x));
printf("sine value of %f is %f\n",y,sin(y));
getch();
return 0;
}
When compile and run above program, this will produce the following result
sine value of 0.500000 is: 0.479426 sine value of 1.000000 is: 0.841471
Program 2
#include <stdio.h>
#include <math.h>
//sin calculator in C
int main()
{ //define variables
float sineValue,inputValue;
//Get input from user
printf("please enter the value to calculate sine: ");
scanf("%f",&inputValue);
//Calculate the sine value
sineValue=sin(inputValue);
//Display the sine value
printf("\nThe sine value of %f is =%f",inputValue,sineValue);
getch();
return 0;
}
When compile and run above program, this will produce the following result
please enter the value to calculate sine: 2.56
The sine value of 2.560000 is =0.549356
