SIN X SERIES

Calculate The Value Of Sin X Series

Source code :-

#include<stdio.h>

#include<math.h>

int main()

{

    float x,sum,f=1;

    int n,i,j=-1,k;

    printf("Enter the value of x in degree: ");

    scanf("%f",&x);

    printf("Enter the number of term: ");

    scanf("%d",&n);

    x=(3.14/180)*x;

    sum=x;

    for(i=2,k=3;i<=n;i++,k+=2)

    {

        f=f*(k-1)*k;

        sum=sum+(pow(x,k)/f)*j;

        j=j*(-1);

    }

    printf("\nThe result is %.2f\n",sum);

    return 1;

}

Input-Output :-

abhi@hp-15q-laptop:~$ gcc sinx.c -lm

abhi@hp-15q-laptop:~$ ./a.out

Enter the value of x in degree: 60

Enter the number of term: 5

The result is 0.87
