In this tutorial, we will discuss Sine function in C programming Language
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 function 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() function 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 – Sine function in C programming
The following example shows the usage of sin() function
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
