Lower riemann sum
WebFor the "lower sum" you take f (x) as the smallest value of f in the sub-interval and multiply by the length of the sub-interval, then sum. For the "left sum" you take f (x) for x the end of the sub-interval and multiply by length of the sub-interval, then sum. WebMar 24, 2024 · For a given function over a partition of a given interval, the lower sum is the sum of box areas using the infimum of the function in each subinterval .

WebRiemann sums with "infinite" rectangles Imagine we want to find the area under the graph of f (x)=\dfrac15x^2 f (x) = 51x2 between x=2 x = 2 and x=6 x = 6. Using definite integral notation, we can represent the exact area: \displaystyle\int_2^6 \dfrac15 x^2\,dx ∫ 26 51x2 dx We can approximate this area using Riemann sums.
