hey thanks a lot bro! that did the trick! u know what i was doing before? i put in the whole equation in there, i did this:

(example)

y=1-x^2 <---i wrote the whole thing out like that and pressed "enter"

but i didnt realize that i dont need to put the "y equals" (y=) part on there!

thanks a lot!!

you're very welcome. The link I gave you seems to be a much better calculator though.

oh no,ur absolutely right, i didn't mean that i was going to use that other one, because i do like the one you gave, its much more user-friendly than that one i was using before! thanks a lot, and i'm sorry if i sounded like i didnt appreciate the link u gave me, because i do appreciate it and i'm actually using it right now.

hey, would any of you know where i could find an equation that would let me graph a hamburger, or fries? i heard that someone once graphed that on their calculator, so i was just wondering if such an equation exists (or any equation that would allow a person to "draw" on there).

thanks btw!

Nah, I wasn't implying that, just throwing out my opinion.

lol they probably just drew it haha... but that would be an awesome function

hey those sound soo cool but i have 2 "disabilities" man, all i see in the "pretty print" is an awesome little square with a red X in the middle and when i tried to graph those on that sweet online grapher, it doesn't at all look like what they described. i think its because the settings are different.

graph of this on the online site :9 * sin(5 * θ)^2 - 2 * cos(θ)^4

Chinese Star? or Mike Tyson in the 7th round? :rofl: (replace the θ with x on the online grapher)..

that was a great site though, thanks a lot, i'm gonna try all those once i get a calculator.
