## Funny Joke – The Integration of Pretty Little Polly Nomial

Once upon a time, (1/T) pretty little Polly Nomial was strolling through
a field of vectors when she came to the edge of a singularly large matrix. Now Polly was convergent and her mother had made it an absolute condition
that she never 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 grounds that it
was insufficient and made her way in amongst the complex elements.

Rows and columns enveloped her on all sides. Tangents approached her
surface. She became tensor and tensor. Quite suddenly, 3 branches of a
hyperbola touched her at a single point. She oscillated violently, lost
all sense of directrix, and went completely divergent. As she reached a
turning point, she tripped over a square root protruding from the erf and
more, she found herself, 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. Was she still convergent, he
wondered. He decided to integrate improperly at once.

Hearing a vulgar fraction behind her, Polly turned around and saw Curly
Pi approaching with his power series extrapolated. She could see at
once, by his degenerate conic and his dissipated terms, that he was up to
no good.

“Eureka,” she gasped.

“Ho, ho,” he said. “What a symmetric little polynomial you are. I can see
you are bubbling over with secs.”

“Oh, sir,” she protested. “Keep away from me. I haven’t got my brackets on.”

“Calm yourself, my dear,” said our suave operator. “Your fears are purely
imaginary.”

“I, I,” she thought, “perhaps he’s homogeneous then.”

“What order are you?” the brute demanded.

“Seventeen,” replied Polly.

Curly leered. “I suppose you’ve never been operated on yet?” he asked.

“Of course not!” Polly cried indignantly. “I’m absolutely convergent.”

“Come, come,” said Curly, “let’s off to a decimal place I know and I’ll
take you to the limit.”

“Never,” gasped Polly.

“Exchlf,” he swore, using the vilest oath he knew. His patience was gone.
Coshing her over the coefficient with a log until she was powerless,
Curly removed her discontinuities. He stared at her significant places
and began smoothing her points of inflection. Poor Polly. All was up.
She felt his hand tending to her asymptotic limit. Her convergence would
soon be gone forever.

There was no mercy, for Curly was a heavy side operator. He integrated by
parts. He integrated by partial fractions. The complex beast even went
all the way around and did a counter integration. What an indignity to be
multiply connected on her first integration. Curly went on operating
until he was absolutely and completely orthogonal.

When Polly got home that night, her mother noticed that she was no longer
piecewise continuous, but had been truncated in several places. But it
was too late to differentiate now. As the months went by, Polly’s
denominator increased monotonically. Finally, she went to L’Hopital and
generated a small but pathological function which left surds all over the
place and drove Polly to deviation.

The moral of our sad story is this:

If you want to keep your expression convergent, never
allow them a single degree of freedom.
