  • Never need that kind of calculator :) Try to graph yourself, it helps :)

    Oh, amazon is quite ok ... some ebay sellers has good return policies .... be sure to check or contact sellers before buying.

  • I really need a calculator since Íll face a lot of difficult equations and I dont have much time. if I graph the equations by hand, ítll take a lot of time and the number might not be accurate. the better technologies get, the more lazy ppl are, right? Grin

  • It's true that ppl are getting more lazy :)

    However, you don't need to be exact, just a few points, first and second derivative, and check limit, you can graph it w/in 3-5min ... the more you practice, the faster you graph ... it helps when you take exams where graph calculator is prohibited.

    if you need help w/ recognizing type of graph w/ some particular equations, I might give you some pointers ... of course if my memory still serve me right Laugh of loud

  • all the engineering classes allow to use calculator and the time to do the problems is not much. all the students were asked to have a Ti 84 or better, so I have to get one for myself. it really sucks.

    I never used calculator for graphing . As mr. mltr pointed out, I graphed some basis equations on paper and used as cheat sheet . I have short term memory, but my cheat sheets are still good a new Giggling Giggling . All my classes did not allow used graphic calculator (because they worry about cheating), all we allowed to simple calculator like in computer . Test for 1 hr, with 5 graphs and other problems, still had time to yawn and wiped sweats and passed with on average and grasped a degree like everyone else . You dónt need to be super genius to pass all the classes ;)


    Student loan - everyone does . That 's why I dream of marrying a billionnair . :blush: :blush: . Everyday I only have a few hour sleep even now - working and studying like crazy . I believe everyone have the same lifestyle as student life - poor, hungry, lack of sleep . Only a few percent of people were lucky to be born with a silver spoon, the rest needs to work whatever they want in their life. In this country, everyone has the same opportunity, it is up to you!!!!! Don't be whiner! Be a winner of yourself ;)


    FYI: I got tons of stuffs via Ebay and half.com

  • I really need a Ti 92 or Ti 94. At this current level, it's not about graphing anymore. It's all about how students think of the problems and how they figure out the solutions. if you have a zero on the test without trying anything and you have a zero on the test with a good attempt to solve the problems but u got the answers wrong; it's totally different, right? I dont think of a calculator as a cheat, I think of it as an assistance to solve the problems faster. Anyways, getting a Ti 92 or Ti94 is mandatory, so I have to get one.

    PS: an average grade wont get me anywhere, so I have no choice but get my GPA with B+ or higher.
