Chapter 9, Problem 56(choose chapter or problem)
Use a graph to show that the inequality is true. What can you conclude about the convergence or divergence of the series? Explain.
(a) \(\sum_{n=1}^{\infty}\frac{1}{\sqrt{n}}\ >\ \int_1^{\infty}\frac{1}{\sqrt{x}}\ dx\)
(b) \(\sum_{n=2}^{\infty}\frac{1}{n^2}\ <\ \int_1^{\infty}\frac{1}{x^2}\ dx\)
Text Transcription:
sum_n=1 ^infty 1 / sqrt n > int_1 ^infty 1 / sqrt x dx
sum_n=2 ^infty 1 / n^2 < int_1 ^infty 1 / x^2 dx
