WebThus, every upper and lower sum of f on [0,1] is equal to 1, which implies that the upper and lower integrals U(f) = inf P∈Π U(f;P) = inf{1} = 1, L(f) = sup P∈Π L(f;P) = sup{1} = 1 are equal, and the integral of f is 1. More generally, the same argument shows that every constant function f(x) = c is integrable and Zb a cdx = c(b −a). eaccessny dos.ny
