If \(\sum {{a_n}} \) converges then \(\mathop {\lim }\limits_{n \to \infty } {a_n} = 0\). The value of the series is. Note that it doesnt really matter which series term is in the numerator for this test, we could just have easily defined \(c\) as. To see this consider the series. Likewise if \(\overline{c} = 0\) then \(c = \infty \) and if \(\overline{c} = \infty \) then \(c = 0\). Because \({a_n} \ge 0\) we then know that we must have \({s_n} \to \infty \) as \(n \to \infty \). Finally, since \(\sum\limits_{n = 1}^\infty {{b_n}} \) is a convergent series it must have a finite value and so the partial sums, \({s_n}\) are bounded above. Lets go back and examine the series terms for each of these. Shopping. nth term test. Therefore, the sequence of partial sums diverges to \(\infty \) and so the series also diverges. Consider the following two series. David Cazenave (2023). Unit 1 Worksheet 11 Steps to solving trig word problems.
