Once In A Blue Moon

I wasn't very good at it, but I did enjoy analysis, and pure mathematics in general. 

Funny how the one pony canonically proven to be good at maths is flabbergasted at seeing the integral equation. Unless that's worry for what putting Pinkie Pie inside a mathematical formula might do to the structure of the universe.

Seeing that your integrand twists reality in a manner typically associated with a work by M.C. Escher would certainly be intimidating. x^x is bad enough.

As an aside, in the adventure 'The Pet Predicament' for the Tails of Equestria RPG Twilight makes a reference to Dijkstra's algorithm, which genuinely impressed me - far too many authors would substitute meaningless babble in place of genuine mathematics.
