The procedure to use the Riemann sum calculator is as follows:

Step 1: Enter the function, upper and lower bound in the input field

Step 2: Now click the button “Submit” to get the Riemann sum

Step 3: Finally, the Riemann sum using upper and lower bound will be displayed in the new window

### What is Meant by Riemann Sum?

In mathematics, the Riemann sum is one of the types of approximation of the definite integral with specified upper and lower bound values. It is mostly used to approximate the area of the function, length of the curves, lines on the graph and some other approximations. The Riemann sum is used to define the integration process. It is a systematic way to find the curved surface area. It is noted that the result of the midpoint Riemann sum gives more accurate value than the trapezoidal rule.
