### Re: I have a function in parametric form. I want it as y=f(x

Funnily enough I had the same idea for audio processing in 1981 and called it "slew rate limiting". Back then there were no chips that could do the arithmetic fast enough, so I asked a friend who did audio frequency design. He pointed out that it was differentiation followed by limiting fo...

I'd say don't get too distracted by the behaviour of the normal distribution. The standard deviation applies to any distribution.

TIL that Henry VIII was 52 inches around and 61 inches high before he died.

Where did you learn that? Most references seem to say he was about 6'1" tall. That's 73".

### Re: spelling and Constants- Inconsistency with the Universe?

Doogly said Pi is all over physics, like flies on shit. You can't just rationalize all your units and make it drop. It needs to be there. I agree with you. So I need to clarify what I was trying to say when I was asserting that it wasn't a physical constant. A constant used in physics may be a diffe...

Basically, I showed that given an odd number, you can find two consecutive integers larger than the odd number that create a Pythagorean triple. I agree that could be a nice example for the OP to have a look at and yes, phrased like that, there's a PT that's both primitive and unique. The question ...

Uhh, gorcee, mdyrud specifically mentioned odd numbers, so your line of argument doesn't address the specific claim being made - it can only exhibit non-unique even numbers.

Ah, but you had one 52 on the left and one on the right of the equals sign. Maybe mdyrud meant that all odd numbers appear in the summands of a unique, coprime, Pythagorean triple?

Nope...

It's common (though not universal) for 64 bit floating point arithmetic to use a 53 bit mantissa, which means you run out of precision in decimal terms at 53 log 2 digits. (You can represent all 15 digit integers precisely, but around 9.5 * 10^15 the trouble starts - hence your figures going wrong a...
