Consider the function f(x) = 1/x for x [1, 2]. Construct a partition on the interval [1, 2] with two subintervals of equal length. Use this partition to compute the upper sum of f and lower sum of f, and then use this result to prove 7 ln(212) 10. Hint: denote the partition as P, the upper sum of f as Uf (P) and the lower sum of f as Lf (P), and recall these were concepts taught in math 1300.
