When I first learned trigonometry in high school, I fell in love with it. I don't always appreciate other forms of math, but for some reason trig struck a chord with me. As strange as it sounds, I was always a bit disappointed at the end of an evening of homework, knowing that I had no more trigonometry problems to work on. To this day, I still feel a little flutter of excitement anytime the words "cosecant" or "arctangent" are mentioned in my presence.
So it is in tribute of this most thrilling of mathematic sports that I drew this cartoon. The pun itself is a throwaway gag, just something to make it semi-humorous. Interestingly, the phrase Elementary, my dear Watson never actually appears in the Sherlock canon. (Kind of like "Play it again, Sam" is never spoken in the film Casablanca.) It's just another one of those signature phrases never actually spoken by the person to whom they are attributed.
