Lower sum method
Weblower sum A upper sum In general, it is rather complicated to compute upper and lower sums. However, if f ( x) is monotonic, the situation is much easier. If f ( x) is increasing on … Web(6.2) The upper integral of f(x) on [a,b] is defined as U(f) = inf(U(f,P)), and the lower integral of f(x) is defined as L(f) = sup(L(f,P)), where both the infimum and the supremum are taken over all possible partitions, P, of the interval [a,b]. If the upper and lower integral of f(x) are equal to each other, their common value is denoted by R b a
