The site looks great.

I found the 10 best movies but I did not find a music section :/

yes

Hello Lionel, how nice of your to drop in :)

This is a great song  :)

How is a ratio like a rate?

They are both comparisions of one thing to another.

eg

miles/hour

red blocks:blue triangles

Show that there is a root for Sinx=x^2-x

I do not know what you mean .. maybe I should but I don't.  

Do you mean:

Show that this has a root?  In other words show that for some value of x,  y=0?

y=sinx-x^2+x

This has the trivial solution of x=0

well you could pull out

4 diamonds, 4 hearts, 4 clubs, 4 spades and the next one HAS to the a fith of a suite.

so that is 17

(5X10^-4)(3X10^-10) 

\(\sqrt{(5*10^{-4})(3*10^{-10}) }\\ =\sqrt{5*10^{-4}*3*10^{-10} }\\ =\sqrt{5*3*10^{-4}*10^{-10} }\\ =\sqrt{15*10^{-4+-10} }\\ =\sqrt{15*10^{-14} }\\ =\sqrt{15}*\sqrt{10^{-14} }\\ =\sqrt{15}*10^{(-14*\frac{1}{2}) }\\ =\sqrt{15}*10^{(-7) }\\ =\sqrt{15}*\frac{1}{10^{(+7) }}\\ =\frac{\sqrt{15}}{10^7}\\\)

sqrt(15)/10^7 = 0.0000003872983346

Come on Alan, ¶   that is not  pi  that is a pilcrow!    I know because I just looked it up ;)

Punctuation mark[edit]

¶ (English name pilcrow or paragraph mark)

Wikipedia has an article on:

¶

Beginning of a section of text.

Beginning of a paragraph.

Thanks Heureka,

Heureka has divided BY 1000

dividing  TO 1000, as the question asks, makes no sense  :/

Hi Alan and Heureka,

None are working for me either.

Do they normally work?

I didn't know we could do matrices on the calc like that.  Thanks Alan :)
