Maths sites

Scientific notation, can't believe you made it out of secondary school without knowing that

e.g. for 3.7 x 10^6, 10 to the power 6 is a million, so would be 3.7 million

That was why I asked it for an answer "in tonnes", so it gave 740 million tonnes as a fairly readable number, instead of 7.4 x 10^11 kilos.

Well, 5^n by itself doesn't make sense, what is n? but 5^2 or 5^3 etc it will handle.

you mean temperature changes in the water? A hurricane is just a heat engine. Converting thermal energy into mechanical work. By allowing it to flow from a hotter to a cooler place.

this has only become visible with the advent of tracking stations such as the picture only Nullschool.

Why? I don't see your logic at all

What does this mean?

Euler numbers? Scientific or E-format which you are using above has nothing to do with "e", the Euler number.

Where what goes?

In Excel (and many other computer applications) 3.7e6 means exactly the same thing. The "e" is a convenient shorthand for x 10 ^. Can also be upper case E.

almost no one uses the 2.7 style 'e'

It stands more for 'exponent' i.e. 10 to the power of...

Still waiting

Where did you get that from?

I never said anything about saturaion And if you have not managed to guess that the heat input to a lower level of the ocean must be massive after a tropical storm you don't follow anything.

Bascally we are talking about strata if you know what strata is. I am looking for a means of heat transfer which I suspect resides in the layer of thicker salt solution below the Warm Pool

That is what I was thinking but the figures that I supplied came from Google searches and unless you are willing to try some investigation of your own you deserve the respect a troll gets.

snipped.

Yet if you multiply 10, 6 times you get 10 million?

10 x 10 = 100 x 10 = 1000 x 10 = 10,000 x 10 = 100,000 x 10 = 1,000,000 x 10 = 10,000,000. No?

I am surprised you made it out of first year physics without knowing that "n" is the exponential.

That's because you want a site to provide answers to random questions, rather than give you the result of a maths problem.

2.71828,[1] and is the limit of (1 + 1/n)n as n approaches infinity, Wikipedia.

That's seven 10s not six. Maybe maths is a bit too hard until you have mastered counting?

How can you hope to understand complex weather phenomena, when you think that 10 x 10 x 10 x 10 x 10 x 10 isn't 1,000,000?

n represents a *general* exponent ... what's 5^2 ? 25 of course, what's 3^3 ? 27 what's 4^n ? without a value for n there isn't an answer.

Yes, yes we all know about natural logs, but what TNP was saying is that in spreadsheet terms 3.7e6 is a shorthand for 3.7 x 10^6 and has nothing to do with 'e'.

Known as Eulers number or constant. I forget which..

I know what a stratum is, and what strata are.

What I can't make any sense of is what you are wittering on about.

Well, if it answers this:

Does anyone know of maths sites for getting quick answers?

you mean? But what is the difference? And if you can answer that can you suggest a likely site?

Yes:

Can't recommend one that turns nonsense into English though...

A much prettier definition of e comes from Euler's identity

e^(i*pi) + 1 = 0

You won't get any sense out of the OP though he is completely deranged.
