    //SINE SERIES (is it correct??)

    #include
    #include
    #include
    void main()
    {
    clrscr();
    int i,k,n;
    float x,s,term;
    s=0;
    term=1;
    i=1;
    puts("Enter the angle");
    scanf("%f", &x);
    x=x*3.14/180;
    puts("Enter the number of terms upto which summation will occur");
    scanf("%d", &n);
    for(k=1;k<n;k++)
    {
    s=s+term;
    term=term*x*x*(-1)/((i+1)*(i+2));
    i=i+2;
    }
    s=x*s;
    printf("the sum of %f is %f", x, s);
    getch();
    }
