#### Transcript of Pretty Equations in Prezi

Here is how I used to show the quadratic formula:
x = -b +- (b^2-4ac)^(1/2)
2a
Not very readable or recognizable
Looks better from here
Write it in Prezi
It may also be
inserted as a picture
Starts getting really ugly, really fast
The best way...
Looks good here...
... and here...
...and even here...
The key is this website:

http://www.codecogs.com/latex/eqneditor.php
Here is where your LaTeX Code goes, more on that later
Here is the file output: Set yours to swf. Its the one vector format Prezi allows.
Here is how we're going to insert our equation into Prezi. Set this to say URL.
LaTeX code for the quadratic formula looks like this:
x =
\frac{
-b
\pm

\sqrt{
b
^2
-4ac
}
}{
2a
}
\frac{numerator}{denominator}
gives us the fraction
\pm
is the +- sign
\sqrt{}
gives us the radical
^2
squares b
LaTeX does take some time to learn, but it isn't too bad if you've ever used an equation editor. There are all sorts of guides on the web if you need them.
Once you have your latex written, here's what you do:
Write your code
Make sure it matches what you want
swf
url
Copy this text
In Prezi, use Insert>Image
Paste that text from the last page in here and press search:
Voila!
Like I said, the LaTeX code can be difficult at first, but once you learn it..
...it's easy to write almost anything
(Pronounced "Lay Teck")
Note: Two changes: first it doesn't seem that you can insert a picture from a search any more. Perhaps they just moved it by I can't find it. You should be able to download the swf file instead and upload it.

Except, of course, that the swf part of code cogs doesn't seem to be working at the moment. Let me know if you find a work around. Thanks!
