Convergence theorem for alternating series. Estimation of the remainder. Absolute versus conditional convergence.
• What is an alternating series?
• What is absolute convergence?
• What is the alternating harmonic series?
• How do you know if an alternating series will converge?
• Does the sum of (-1)^k/2k+1 converge or diverge?
• How do you estimate the nth remainder of a converging alternating series?
• How do you estimate the difference between the sum from k=1 to infinity of (-1)^(k-1)/k and its 100th partial sum?
• What is conditional convergence?
• What are alternating p-series?
• When do geometric series converge absolutely?
• For what values of x does the sum of x^k/k converge absolutely, converge conditionally, and diverge?
• Why does it matter if a series converges absolutely?
Alternating series and absolute convergence are defined and explained with several examples. Some very interesting and helpful examples are included. The geometric series, alternating p-series, ratio test, and root test are used in finding absolute and conditional convergence. This is a very useful lecture in Calculus.
