Program to calculate sine value of given angle.

Program to calculate sine value of given angle.

Program Code:

#include<stdio.h>

#include<conio.h>

#include<math.h>

#define PI 3.142

int main()

{

int i, degree;

float x, sum=0,term,nume,deno;

clrscr();

printf("Enter the value of degree");

scanf("%d",&degree);

x = degree * (PI/180); //converting degree into radian

nume = x;

deno = 1;

i=2;

do

{ //calculating the sine value.

term = nume/deno;

nume = -nume*x*x;

deno = deno*i*(i+1);

sum=sum+term;

i=i+2;

} 

while (fabs(term) >= 0.00001); // Accurate to 4 digits

printf("The sine of %d is %.3f\n", degree, sum);

printf("The sine function of %d is %.3f", degree, sin(x));

getch();

}

Output:

Enter the value of degree

45

The sine of 45 is 0.707

The sine function of 45 is 0.707
