Pretty Little Polynomial and Curly Pi
Once upon a time (1/t) pretty little Polly Nomial was strolling across a field of vectors when she came to the boundary of a singularly large matrix. Now Polly was convergent, and her mother had made it an absolute condition that she must never, ever enter such an array without her brackets on. Polly, however, who had changed her variables that morning and was feeling particularly badly behaved, ignored this condition on the basis that it was insufficient, and made her way in amongst the complex elements.
Rows and columns closed in on her from all sides. Tangents approached her surface, and she became tenser and tenser. Quite suddenly, two branches of a hyperbola touched her at a single point. She oscillated violently, became unstable, lost all sense of directrix, tripped over a square root that was protruding from the erf, and plunged headlong down a steep gradient. She was completely divergent by the time she reached the turning point. When she rounded off once more, she found herself inverted, apparently alone in a non-euclidean space.
She was being watched, however. That smooth operator, Curly Pi, was lurking inner product. As his eyes devoured her curvilinear coordinates, a singular expression crossed his face. He wondered, was she convergent? He decided to integrate improperly at once.
