Question

k Σ. 5. Show that >In(k1. This shows that the harmonic series diverges. n=l 1 to a Hint: Compare definite integral. Like Exercise 4, you will want to find a function n n=1 f(x), but this time you want to show that ^> f(x) want to draw a picture to help visualize it. This time, think of left-hand Riemann sums with Ax = 1. (Notice that the interval was This is very similar to an exercise you did on a previous homework, so you might want to look back at that for guidance. on the interval n, n+ - 1]. Again, you might [n, n1 instead of [n - 1, nl, like it was in Exercise 4.)
