  1. For the function y=6, the value of area under the curve using the approximation method would be completely accurate.
  2. a. True
    b. False

  3. Decreasing the length of the interval will imporve tha accuracy of the approximation.
  4. a. True
    b. False

  5. Increasing the value of the variable width will :
  6. main(){
      int a , b , width , i;
      double sum ;
      scanf("%d%d", &a; , &b; );
      sum = 0 ; width = 1 ; i = 0;
      for ( i = a ; b >= i ; i += width){
        sum = sum + cos(2*Pi/13*x) * width;
      }
      printf("Integration value = %d", sum);
    }
        
    a. Improve the approximation
    b. Will not have any affect
    c. Make the approximation worse
    d. May improve or make worse depending on the interval

  7. An approximate solution may be as good as the accurate solution for purposes.
