Amazing!

EDIT 2: Ive found an error with the graphing function. When I graph x^2 + 8x, it draws a line instead of a parabola. Also, would like to request a feature: implicit functions with derivatives. This would the make the app soo much better. Anyways, I use this app daily and its still amazing, so my rating is still 5/5.

EDIT: With the new update, my requested features were added along with others like getting an approximate number for logs. 5/5! Definitely the best symbolic calculator for iPod and iPhone users.

The only feature that you should add is the ability to plot the inverse trig functions (csc, sec, cot). Right now I can graph it as (sinx)^-1 though (for csc). Once this is implemented, its a definite 5 star.
