You can say that when someone can bake something like this for Tau.  ;D

I would love to have a tau button on my calculator.  A lot of EE calculations require 2 * PI as a value entry, and saving a couple of button presses would save a lot of grief.

Is there an e day? There should be one. e makes calc so easy (unlike sine, cosine, tagent, and the rest of the trigonometry cabal).

I don't know. Ask Al, this stuff usually has to be ran past him before it can be approved. He is the Lord of Numbers.

Impure Mathematics:
The Adventures of Polly Nomial
Richard A. Gibbs
The Best Of The Journal of Irreproducible Results, 1983

Once upon a time (1/t), pretty little Polly Nomial was strolling across 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 must never enter such an array without her brackets on. Polly, however, had changed her variables that morning, and, feeling particularly badly behaved, she 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, three 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 which was protruding from the erf, and plunged headlong down a steep gradient. When she was differentiated once 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 function behind her, Polly turned round, and saw Curly Pi approaching with his power series extrapolated. She could see at once, by his degenerate conic and his dissipative terms, that he was bent on no good.

"Eureka!" she gasped.

"Ho, ho!" he said. "What a symmetric little polynomial you are. I can see that you are absolutely bubbling over with secs."

"Sir," she said, "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 said.

"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.

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 to smooth her points of inflexion. Poor Polly. All was lost. She felt his hand bounding to her asymptotic limit. Her convergence would be gone for ever.

There was no mercy, for Curly was a heavyside operator. He integrated by parts. He integrated by partial fractions. The complex beast even went all the way round, and did a contour integration. What an indignity! Curly went on operating until he was completely and absolutely orthogonal.

When Polly got home that evening, her mother noticed that she had been truncated in several places. But it was too late to differentiate now - the seeds having been sown. As the months went by, Polly increased monotonically. Finally, she generated a small, but pathological, function, which left surds all over the place, until she was driven to distraction.

The moral of this sad story is this: If you want to keep your expressions convergent, never allow them a single degree of freedom.

Oh thanks Skipmuck! I can rest easy now, at least until Jan 27 and/or Feb 7th when The Par-Tay™ will happen!

This guy goes to a park and he sees a pair of snakes slither by.

He says to them, "Mr Snake, where are the little snakes?"

Mr Snake replies, "We can't multiply, we're adders. "

The guy is satisfied with the answer and finishes his vacation in the park, then goes home.

He comes back the following year and this time he sees Mr & Mrs Snake with a bunch of baby snakes.

He asks them, "Mr. Snake, I thought you couldn't multiply?"

Mr Snake replies, "We can't, but the park ranger built us a log table last summer."

Probably from that peach tree you gave me. Instead of growing normally the roots grow out, up, and around. They never stop!
