We live in a three-dimensional world. Things have height and width and length. In a two-dimensional world, life is different. You never ask a child how tall they are, or even which way is up. The clouds never gather overhead, and a little rain doesn't necessarily fall. If you remove a dimension from your world, what would it look like? How would sports be different? If there were no up or down, what would pineapple upside down cake taste like?

Spoiler alert: May involve basic calculus, but nothing you can't handle.



You can write X-square as X added to itself X times, Right?

As in 5^2 =5+ 5 + 5+ 5 +5=25. Okay?

I mean

Let Y = X^2 = X + X + X +X +... X times,

But if you differentiate the two expressions with respect to X

if you take Y=Xsquare, differential is dY/dX = 2X

and otherwise,
its
dY/dX=1+1+1+1+.....1 X times = X


But this curve can have only 1 tangent at a point, it is a parabola , right?

So if the slope is same,

2X = X
=>2=1!!!!!

Howzzat????

A, B, and C are different digits, each of AB and 7C is a 2-digit number, and each blank space represents a missing digit. What is the value of each of A, B, and C?

____7 C__
AB) _ _ _ _
_ _
______
_ _ _
_ 2 _
_____
0

Note that you will need to write the problem to reflect the proper spacing, e.g. the 7 in the quotient should be above the 3rd digit of teh dividend.

Is there anything going on physiologically / biochemically that would account for a person becoming really depressed or prone to crying while sick?

I've been sick with the flu for over a week, and now bronchitis, and I find myself extremely sad at times, and crying -- sobbing even -- at the drop of a hat. Is that normal?

Following on from the brilliant moon ballon question and how it would react on the moon, which most people thought would smash to the ground much like a rock, what would happen if a rock, say the size of a ballon hit the moon, it would have so much power and destructive potential so why is it that the moon isnt smashed to peices yet! you can see destruction on the moon but given the amount of space debris it should be destroyed or so I believe if given that the moon balloon would hit the ground like a rock?

I have 2 inputs A & B. Input to A can be 150, 300, or 600. B input can be 0 to infinity. Here are the variables below.

If A=150 and B is less then 500, multiple B*0.29
If A=150 and B is between 500 to 5000 then multiple B*0.25
If A=150 and B is greater then 5000, multiple B*0.20

If A=300 and B is less then 500, multiple B*0.39
If A=300 and B is between 500 to 5000 then multiple B*0.35
If A=300 and B is greater then 5000, multiple B*0.30

If A=600 and B is less then 500, multiple B*0.49
If A=600 and B is between 500 to 5000 then multiple B*0.45
If A=600 and B is greater then 5000, multiple B*0.40
Thank you, AL
