Parabola and Ellipse
I have been a little Geometric of late, and have produced:
Ellipse and Perimeter of Ellipse
Conic Sections (those images took over a day, using PovRay)
I hope you all enjoy reading, and I would also value a critical mathematical eye to correct any mistakes (I am only human!)

Re: Parabola and Ellipse
I like it! The conic sections are awesome, and i never knew that ellipse perimeter couldn't be solved with integration. Very cool!
A logarithm is just a misspelled algorithm.

Re: Parabola and Ellipse
Ooh, these look very interesting. Some of the most advanced pages you've done, particularly the one on the perimeter of an ellipse. I can't see any mistakes though, although that could be because some of it's over my head. 
For example, what on Earth are half-integer factorials all about?
Why did the vector cross the road?
It wanted to be normal.

Re: Parabola and Ellipse
(1/2)! etc, the Gamma function deals with them. Very interesting subject, and I hope (one day) to write a page about it

Re: Parabola and Ellipse
I added a small section about it to the end of the page on Factorial Function !

Re: Parabola and Ellipse
What about the latus rectum?
There are 10 types of people in the world, those who understand binary, those who don't, and those who can use induction.
