I am not sure how would I work this problem.
Any help would be appreciated. Estimate ln 1. 5 = Integral from 1 to 1.5 dt/t using the approximation 1 2 [Lf (P) + Uf (P)] with P = {1 =8/8, 9/8, 10/8, 11/8, 12/8=1.5}

what are Lf(P), Uf(P), are they just two diffrent functions, or?
if they are functions do they hve any other property given?

They mean Riemann sums with Lower/Upper function values. In this case, it correspondes to Left hand/Right hand sums.
I dont understand zingorias 3rd last and last line very well, what exactly have you tried so far? PS This should have been posted in a homework forum.
