  In each case, if the limit exists (or if both limits exist, in case 3!), we say the improper integral converges. If the limit fails to exist or is infinite, the integral diverges. In case 3, if either limit fails to exist or is infinite, the integral diverges. RyanBlair (UPenn) Math104: ImproperIntegrals TuesdayMarch12,2013 9/15

  3 This is very straightforward to solve. We seek the angle or angles which have a cosine of √1 3. Now if x lies in the interval −π < x < π then x −0.615 must lie in the interval −π − 0.615 < x −0.615 < π −0.615 Figure 3 shows a graph of the cosine function over this interval. The angle on the right of the diagram which has a ...

In part (b) the student gives the correct series for cosine. There is evidence of adding the correct two series but the addition is incorrect, so only 2 of the possible 3 points were
