If you be rude to me Zegroes it might be like having a unicorn for an Avitar.

THAT'S WHAT I KNOW!

It measures the size of an angle or the temperature.  Depending on context.

It calculates nothing!

I want you to look at this post.

$$16^{1/2}=\sqrt{16}=4\\\\

16^{-1/2}=\frac{16^{-1/2}}{1}=\frac{1}{1\times 16^{+1/2}}=\frac{1}{\sqrt{16}}=\frac{1}{4}$$

NOTE: The 1 that was on the bottom stayed on the bottom.  I put the one on the top because there was nothing else there. when there is nothing else you put a one. does that make sense? 

Whenever anything is raised to a negative power you swap it to the otherside of the fraction line and change the negative power to a positive power.

$${\mathtt{\pi}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{4.5}} = {\mathtt{31.808\: \!625\: \!617\: \!596\: \!656\: \!5}}$$

I just did this on the web2 calc - I used the math(inpu=Result) key above.

Maybe you are putting the brackets in the wrong place?

$$6C4(0.60)^4(0.40)^2$$

$${\left({\frac{{\mathtt{6}}{!}}{{\mathtt{4}}{!}{\mathtt{\,\times\,}}({\mathtt{6}}{\mathtt{\,-\,}}{\mathtt{4}}){!}}}\right)}{\mathtt{\,\times\,}}{{\mathtt{0.6}}}^{{\mathtt{4}}}{\mathtt{\,\times\,}}{{\mathtt{0.4}}}^{{\mathtt{2}}} = {\frac{{\mathtt{972}}}{{\mathtt{3\,125}}}} = {\mathtt{0.311\: \!04}}$$

10P10

$${\left({\frac{{\mathtt{10}}{!}}{({\mathtt{10}}{\mathtt{\,-\,}}{\mathtt{10}}){!}}}\right)} = {\mathtt{3\,628\,800}}$$

or just 10!

What do you want me to do with this?  discuss it?

I can see straight away that 

$$x^3-432\ge 0\\
x^3\ge 432\\
\mbox{Hence}\\
x\ge \sqrt[3]{432}$$

I can also see that as x approaches infinity y plus or minus infinity.

I can 'see' that the cuve will be symmetrical about the x axis. (This is the line y=0)

Maybe that is enough discussion.

Here is the graph.

I am sorry Feitan but this is not really correct.

pi is a number.  It is the answer when the circumference of a circle is divided by its diameter. In other words it is the number of times that the diameter will go into the circumference of the circle.

It is an IRRATIONAL NUMBER. This means that it cannot be represented exactly as a fraction. And from that it also follows that it can not be represented exactly by a terminating or a recurring decimal.

These approximations are sometimes used

3.14 or 3.142 or

$${\frac{{\mathtt{22}}}{{\mathtt{7}}}} = {\mathtt{3.142\: \!857\: \!142\: \!857\: \!142\: \!9}}$$

or the approximation from the web2 calc is

$${\mathtt{\pi}} = {\mathtt{3.141\: \!592\: \!653\: \!589\: \!793\: \!2}}$$

The web2 calc is much more accurate than the others but it is not exact.

As I said Pi is an irrational number and cannot be written exactly as a number.

Thanks Chris.
