Unhappy *THROWS TI-83 PLUS OUT OF A WINDOW* - February 20th 2013, 12:35 AM




i am so stupid oh my gosh!!!
i started out this class with the wrong calculator (not the ti-83 plus, which is what we needed) but i thought i'd be okay

then my teacher only showed how to work on the problems on a calculator i didn't have. so many shortcuts that i had to find the long way to.
then we started doing stuff i COULDN'T do without the ti-83 plus, but she said i could check one out instead of buying one for $80 at walmart. downside: they all needed batteries. being broke, it took me like 2 weeks to get the batteries and by then the class was too far ahead of me.

i have no idea how to use this calculator
the help in the book is useless
idk if i could ask for a tutor at this point and i need this class to graduate.

it's really stressing me out
does anyone have any help sites or study tips or even a guide on how to put a f(x) equation into this godforsaken contraption

(this is probably inappropriate, but if anyone has taken precalc and is willing to help me out with some stuff PLEASE I WILL LOVE YOU FOREVER AND BE INDEBTED TO YOU)

It's been a long time since I've taken pre-calculus, so unfortunately, I wouldn't be much help. Have you considered asking your teacher for help after school? They are generally willing to do so, if you ask far enough in advance.

I'd also suggest doing a Google search. There are things like this cheat sheet that explain what all the buttons do. There's also this tutorial, and I see a few sections that talk about graphing functions.

I think talking to your teacher would be a good idea. S/he would probably be willing to help you figure it all out and get back on track. Also, does your class have a tutor for precalculus? If so I think you would be able to get help from them as well; they would know how to use the calculator about as well as the teacher. Lastly, if you are close to anyone in the class you might be able to ask them how to use the calculator. You would probably only want to do this with someone you know is doing well in the class though so that you know they are teaching you correctly.

I don't know if you are in college or in high school, but if its college you could meet with your teacher during their office hours? Or make an appointment with her if they do that in high school?

"Setting boundaries is not a more sophisticated way of manipulation - although some people will say they are setting boundaries, when in fact they are attempting to manipulate. The difference between setting a boundary in a healthy way and manipulating is: when we set a boundary we let go of the outcome."

If you still need help learning how to use your calculator, I might be able to help out. It's been a while since I took precalculus, but if you could PM me some of the problems you need to do for homework, or attach a picture of the homework sheets/pages with the problems on it, I could take a look and try to help out.

Otherwise, I agree with everyone mentioning that you should talk to your teacher and ask for some help trying to figure out how to do the work (it's is technically his/her job to help you do the problems, after all).
