How To Use The TI-84 Graphing Calculator

Sorry but compared to CASIO texas is just s**t. (eg. cfx-9850). Casio is much easier to use as well. Your school/college may tell you get a texas because the lessons are made for Texas calculators. That might be true, but the Casio calculators are SO easy to use that you dont need any help with it. everything is pretty selfexplaining. you can compare it to "windows/casio and MSDOS/Texas". Texas hasnt got any intuitive menus etc. its just hard to use. apart from that a casio is just easier to use its faster as well. I dont mean the calculator speed itself. i mean the time which is taken to use the different functions. on average my mates need about 1,5 - 2x as long as i do with my casio.... (ps: if u ask yourself, why every school recommends texas, thats because texas sponsors everything, from the Alevel to SACE to IB...) ps²: everyone who will buy a texas calculator will know, what the "times" symbol etc is for lol.... its pretty bad. if u would have explained integration etc on a calculator, that would have helped but this is just useless hehe....
