got out my calculator now... great formula for when the nine on the calculator isn't working any more... (who needs more than three digits after all..)

A different, yet valid approach.

(the expression on the left hand side of aparaxas formula gives 18,999098... or something like that, so its a close approximation to a fancy way of writing 19...) (and if the 9 on your calculator isn't working anymore and you don't want to write 8+1 this is another way to go, no, not very funny)

Count Kook: When the stirring's done, can I lick the spoon?

Professor Weirdo: Of course! A-ha! Of course! Now for a pinch of tenderness But I must use only a touch, For without a touch of tenderness He might destroy me!

[Kook accidentally knocks Weirdo's arm]

Professor Weirdo: OOPS! Too much!

Professor Weirdo: Better hold your breath; it's starting to tick!

Count Kook: Better hold my hand; I'm feeling sick!

I went to a Catholic school in 7th grade. We were still learning fractions.

I wasn't in Catholic school but I know I didn't encounter quadratics before eighth grade, and I was in "advanced" math. Most of my classmates didn't get it until 9th grade.

I was, in fact, from 5th grade until 8th grade. John Kerry and I have that in common!

we certainly hope so.

An *easy* formula to extract a square root (cover of aparxa from a famous Newton standard) :

If you need the sqrt of x (ex 34), take the closer perfect number r^2 of x (36). An approximation of the sqrt of x (34) is the fraction (mean of two numbers)/r = 35/6

If M is this mean (M=35), and b the half difference of the first numbers (b=(36-34)/2=1), then

sqrt(x) =approx= M/r

and for fans of mental calculation, we can use this second order formula :

sqrt(x) =approx= M/r -b^2/(2Mr) =example= 35/6-1/(2*35*6)=2449/420

I also have a FABULOUS formula to calculate inverse numbers, will expose it later.

Is Baire's Theorem far behind?

[DukeCity]

Good formula to know:

3,2,2,1

3 parts vodka

2 parts triple sec

2 parts cranberry juice

1 part lime juice

=

Perfect Cosmopolitan!

(edit to mention that formula arrived at after EXTENSIVE research... )

Did I have a formula? I wonder what it was.

I've had to memorize that damned formula four separate times in life, and I still can't remember the damned thing...

I've looked at that three times already (once for each posting) and I've only just seen it. Does it really go on like that forever?
