The Riemann Sum is then given by the general formula: ∑i=1nfxi⋅b−an There are five main types of Riemann Sums, depending on which pointxiis chosen to determine the height: • Right Sum: the right endpoint of the subsegment ...
This means that we have $x_i = \left\{\dfrac{1}{2}, 1, dfrac{3}{2}, 2\right\}$. Apply the formula for the Riemann sum using the right-hand and left-hand rules to approximate the area under the curve of $\int_{0}^{2} 4 – x^2 \phantom{x}dx$....

Step 8. To compute the lower Riemann sum, Low n , you must find the absolute minimum of the function f(x) on each of the subintervals [x i−1 , x i ]. Call this absolute minimum Min i . Then the lower Riemann sum is given by the formula Low n = ∆x(Min 1 +Min 2 ...
We can either place the rectangles so the curve is on the left or right as follows. Depending on the curve one or the other gives a reasonable approximation. You can see in the above examples, the "left" approximation will be too small (the sum of the rectangle areas is less than the...
