The limit comparison test gives us another strategy for situations like Example 3. Limit comparison test (LCT) for improper integrals: Suppose f(x) and g(x) are positive, continuous functions deﬁned on [a;1) such ... According to the limit comparison test this tells us that suma_n and sumb_n are either both convergent or both divergent. Since b_n=1/n, we see that sumb_n is divergent (it's the harmonic series), so we can conclude that suma_n=sum_(n=1)^oosin(1/n) is also divergent.In order to see the formula that he is referring to you need to rewrite (1/2)^n in the form ar^k. If you remember from an earlier video this then converges to a/ (1-r) provided that -1<r<1. With this in mind you can rewrite (1/2)^n in the form ar^k or 1* (1/2)^k the sum of which is a/ (1-r) or 1/ (1-1/2) which is 1.Oct 17, 2011 ... The limit limn→∞(−1)n does not exist, so the.
