Calculus/Sequences and Series/Exercises
Each question is followed by a "Hint" (usually a quick indication of the most efficient way to work the problem), the "Answer only" (what it sounds like), and finally a "Full solution" (showing all the steps required to get to the right answer). These should show up as "collapsed" or "hidden" sections (click on the title to display the contents), but some older web browsers might not be able to display them correctly (i.e., showing the content when it should be hidden). If this is true for your browser (or if you're looking at a printed version), you should take care not to "see too much" before you start thinking of how to work each problem.
Consider the infinite sequence
- Is the sequence monotonically increasing or decreasing?
- Is the sequence bounded from below, from above, both, or neither?
- Does the sequence converge or diverge?
Assume that the nth partial sum of a series is given by
- Does the series converge? If so, to what value?
- What is the formula for the nth term of the series?
Sums of infinite series
Find the value to which each of the following series converges.
Convergence and divergence of infinite series
Determine whether each of the following series converges or diverges. (Note: Each "Hint" gives the convergence/divergence test required to draw a conclusion.)
Absolute and conditional convergence
Determine whether each of the following series converges conditionally, converges absolutely, or diverges. (Note: Each "Hint" gives the test or tests that most easily lead to the final conclusion.)
Find the Taylor series for the following functions centered at the given values.
