Inverse functions?

i miss high school algebra
anybody care to help explain to me how one infinity could be bigger than another ?

The rate at which it approaches infinity?

This thread just made me realize how much I miss math!

Not!

ah i have the ti 89 titanium also... actually dont like it very much. liked the 83 more for graphing. untill i got to calc I II and III... 89 does derivatives and intergrals FTW so if you have to go any further in math keep the 89

The TI-89 Titanium is a gift from god... Once you get use to it, its fricking amazing. Switching from an '86 to an '89 Ti took some getting use to though. Being able to solve EE equations and crap is cool as hell.

Just don't get to reliant on it, alot of colleges you can't use a calculator in calc I/II so don't use it as a crutch.

Exactly.

As x approaches +Inf x^3 > 2x

They both approach infinity, but one does it a Hella lot faster

I've used an 84 Plus I think... liked it better at first, but I got to know this calculator pretty **** well... it's amazing. My favorite feature is "solve" //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
RE: Functions, when they ask me to make a chart of the relation: R={(1,2),(-3,4),(0,-4),(1,0)} how do I do it? I have to type it in a text box, so I don't think they mean make a table?

right before i graduated high school they started offering classes in how to use all the functions on these calculators. its a ***** trying to learn some of these functions on your own.... and half my professors couldnt use one if their life depended on it

You put the coordinates into the plot list. L1 is x-coordinates, L2 is y-coords

Buttons for it are

STAT > Edit... > Then you're at the list

Oh, and make sure you have Plot1 turned on

No stat button on the 89... confused

Hold on, lemme go find my other calculator. I thought you said 83 for some reason

Got the manual??

Not on me, I'm at work doing my homework //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

from the main screen when your turn the calculator on... i think its under xy table... that menu before you go to the home screen

Sounds right eclipse but I can't confirm it. My dumbass friend has my other calculator right now because he lost his.

wrong, you examine the cardinality ( the number of countable elements in it )

but thats set theory, which will give you a headache without a proper introduction

oooo, you got me there. I got carried away with the making a graph thing for the vert line test.

Im not sure enough how to do this one after all.
