Completing the Square

Two more pages done! Please have a look at Completing the Square and Derivation of Quadratic Formula.

Hopefully you will find them interesting, and will let me know of any errors or omissions.

I have debated with myself if I should "LaTeX" all the formulas or leave them as plain text. Or maybe just do some of them. Hmmm roll

Re: Completing the Square

If you feel like taking the extra time, LaTeX makes it look prettier. Things like "√" from plain text aren't the most exciting displays of mathematical notation. The only thing on those pages that would have a big improvement thanks to LaTeX are the "√"'s though. Some of the fractions could be "\frac"ed too, for optimal looks.

Re: Completing the Square

if you need a slave btw, I'd be more than happy to rewrite as LaTeX

not finished, I know - but I have to stop now.. If there are any mistakes, it's because I'm tired. It's 4:17 AMsleep

Re: Completing the Square

Late night effort indeed!

I replaced the ones that really needed replacing. It is now a mix, but hopefully a good mix. You see, text is reliable and low bandwidth. But LaTeX is obviously better at things like sqrt and fractions, but is another image to download, and it is hard to match plain text with LaTeX (they don't always line up).

So I tested them and had to make a decision.

What do you think? Here it is: Completing the Square (you may need to refresh if you see the old one)

Re: Completing the Square

I think so ... but it is looking better with the LaTeX.

Re: Completing the Square


(dont know if this is needed)




   
d = b/2a && e = c - b2/4a have already been made, just copy paste smile

















phew... Hope there are no mistakes smile

Re: Completing the Square

OK. done, and looking pretty good!


These are for the Derivation of Quadratic Formula page (I started with yours, Patrick, and carried on):
