       Estimating the area under a curve typically involves quite a bit of arithmetic but shouldn’t be too difficult conceptually. The process should be straightforward after you do a few problems.

       The problems on expressing a given Riemann sum as a definite integral don’t always have unique solutions.

       To evaluate the problems involving Riemann sums, you need to know a few summation formulas. You can find them in any standard calculus text if you don’t remember them — or you can derive them!

Calculating Riemann Sums Using Left Endpoints

       519–522 Find the Riemann sum for the given function with the specified number of intervals using left endpoints.

      519. , ,

      520. , , . Round your answer to two decimal places.

      521. , , . Round your answer to two decimal places.

      522. , , . Give your answer in scientific notation, rounded to three decimal places.

Calculating Riemann Sums Using Right Endpoints

       523–526 Find the Riemann sum for the given function with the specified number of intervals using right endpoints.
