To be fair, if you know what the answer is to the question ahead of time, you will not effectively practice when solving the problems.

The key is to pair off terms to cancel the complex exponential. By combining Euler's formula with the trig rules that , you can see that . Then you will be left with a summation of a constant.

I saw the 42 answer, but passed it off as that Hitchhiker's Guide to the Galaxy joke! I solved it on a spreadsheet, since it was so simple, and was pleasantly surprised that (1) the answer was actually 42, and (2) I still knew how to do this.

I've used Calculus twice i real life; once to verify to the Nuclear regulatory Commission some pour-and-measure dipstick volume marks on a cylindrical transformer fluid tank unevenly buried on its side; and one to determine the amount of fill dirt my sister needed to turn her above-ground basement into an underground one (max slope, peferred footprint, and size of rectangular cube NOT filled).
