excel equation scientific notation

(hover cursor over box to see image of formula that cannot be copied correctly from excel (rabble rabble rabble))

So I made a 6th degree equation from a trendline in excel...

If anyone can tell me what this is supposed to mean they can have a cookie* >.>. I know scientific notation, but it seems to me that regular SN is not good enough for microsoft, I mean, why would they put another value after the E? thats like saying -6x10^1 - 06x10^6 which makes no sense since the powers are sorted and this is a 6th degree polynomial... err.... have they invented their own convention?

also.. anyone who can tell me if it is possible to calculate a first order derivative in excel can have another cookie*. I suspect not since no Google searches I did told me how and its not in the excel functions... but I may have missed it.

Thanks!

That notation isn't Microsoft's invention: the capital 'E' reads as 'times 10 raised to the power', so -6E-6 reads as 'minus six, timers 10 raised to the power minus six'. So in numbers: -6/1,000,000 (minus six divided by a million).

kind regards,

>.< ugh

And that I understand since math in high school. however

regular SN form is:

1.8*10^4 or 1.8E4... etc

But if you look at it (more closely at the first term in the polynomial) you will see that this show as
-6E-06E^6 .
I say, this makes very little sense.
it would work out to be -6*10^1 - 06*10^6
or
-6*10*-06*10^6 which also means nothing

which makes absolutely no sense at all as there is already a constant term and as I mentioned in my original post, not standard in any way that I can see.

Which brings us back to my original question: What does MicroSoft intend this to mean?

But if you look at it (more closely at the first term in the polynomial) you will see that this show as
-6E-06E^6 .

That is not what I see from that picture you posted; I see -6E-06x^6 which makes sense ... or I completely misunderstand your question.

kind regards,
