I get 2140.View attachment 2360
(a.)Find the Riemann sum for this integral using the right-hand sums forn=3.
(b.) Find the Riemann sum for this same integral, using the left-hand sums forn=3
I have tried the problem a few times, but i cannot get the right answer. I am getting 3832 for the right hand.. please help
Sorry I typed too fast. Try 21402060 was not correct. the x values i am using are 6,7,8,9,10,11 for the right hand values...
But n = 3, not 6.2060 was not correct. the x values i am using are 6,7,8,9,10,11 for the right hand values...
What answer does the book give?yes its n=3. i also tried 7,9,11 but the answer was not correct. i even multiplied by delta x 2 after adding them together.
With n as three we divide the range over which x is to be integrated into 3 equal parts. The range here runs from 5 to 11. So each dx = 2.ok i did not multiply everything by 2 before the end. do you know what numbers for the left i would use?
