I need to call my Calculus Professor to figure out which shipping method is better. I need to use Fourier transform in order to calculate the cost-benefit ratio of the shipping methods.
I read the news just today that James Stewart, the mathematician who authored books on Calculus, died on December 4th, 2014.
I took a look at my bookshelf and immediately found a Calculus Textbook that Stewart authored. Stewart was a violinist and that explains why his books feature violin on the cover.
