I need a graphing calculator for high school and I'm trying to decide between a fx-9860gii or a ti-84 plus/ ti-84 plus silver edition.

Can you please explain their differences?

And are casio graphing calculators similar to texas instruments? (If my teacher is explaining how to do something on a ti-84, will I be able to follow along on a fx-9860gii?)


Thanks!

Welcome to UCF! We look forward to seeing you in the forums. If you haven't already done so, why don't you introduce yourself here: http://www.casiocalc...?showtopic=5677

The TI-84 Plus Silver has the same functions as the FX-9860GII. Because the OS's are different, you may not be able to follow along with some of teacher's instructions, however, a general knowledge of the operating system will in most cases suffice. In fact, many math and science books have help/tips for TI and Casio calculators, so you should be all right. Of course, if you can't understand/figure out how to do something, you can post the question here.

If you do decide to go with casio, I would recommend buying the FX-9750GII which is 20-30 dollars cheaper than the FX-9860, and hacking it with the hack explained here: http://prizmwiki.omn...860GII_Tutorial

Just to clarify, if I hack the 9750, will I get the exact same functions as the 9860? And is there any chance of "bricking" the calculator if I hack it?

Also, casio's website says that the 9750 has just 26kb of memory. Does that mean I can't add in extra programs? If so, do you think the extra memory on the 9860 is worth the 20-30 dollars more?

Thanks again!

Hacking a 9750 is really safe, you won't brick your 9750 as long as you follow the instructions. I have already hacked my 9750 easily.
A hacked 9750 is equal to a 9860 except the backlight. 9750 has 64KB "main memory" and 1.5MB "storage memory", which is equal to 9860's. In my opinion, it's no need to choose a 9860 since a hacked 9750 can do everything that a 9860 can do.

yes. you get exactly the same amount of memory and all the functions. Like jinzihao said, all your missing out on is the backlight and SD card slot. I think that you dont need either, unless you use your calc as a 1 speaker mp3 player (There is an add-in that does that, but like i said, it only uses one speaker)

So, no, I dont think the fx-9860 is worth the 20 bucks.
