How to find indefinite integral on TI 83?

morganmorgan Posts: 48Registered User Junior Member
edited February 2012 in AP Tests Preparation
question same as topic.

say I want to find the integral of (3x+9)/(2x^2+17x+8)
Is it possible to find this integral using TI 83 alone or Is there any type of program you can download and solve the indefinite integral on the TI 83.

Any help would be greatly appreciated. Thanks.

    bump, does anyone know it?

    you have to dowload a program from like texasinstruments.com I think that it is called like the calc package. YOu shoulda got an 89, theyre so much better.

    ye, TI 83 sucks on that part. also, Can you provide me a link to that program, beacuse when I typed calc package on the search button on that webside, there are so many links pomps out, and I am not sure which one to choose.

    Thanks!

    Never mind. I found it. Thanks!

    What? There's a TI-83 program that'll do symbolic integration? That's news. Enlighten us.

    mind posting that link for me? I can't seem to find it.
  • morganmorgan Posts: 48Registered User Junior Member
    it actually does not exit. Sorry!

    haha, okie. I have a TI-84, but I think they work the same way:
    go to Math --> fnint (9) , then put in the equation:
    fnInt(equation,x,lower limit, upper limit), hit enter
    and that's it!

    INDEFINITE integral! My Casio FX-115ES Plus can do a definite integral.

    haha, casio used to be the best...

    The FX-115ES Plus is hands-down the best non-programmable calculator there is. For non-graphing programmable calculators, I'd probably go with an HP 33s, and for graphing programmable non-CAS calculators, I'd go with a TI-84 Plus. This still isn't helping with the fact that the TI-83/84 isn't able to symbolically integrate.

    ohhh well, anyway, I think it's the best to solve problems w/out calculator, I'm anti calculator... well, except that I need it for science

    I don't know how to take the indefinite integral of a certain equation. All I know is how to get the answer of a bounded integral with TI-83.

    TI-83 plus is incomplete because it lacks the other half, TI-83 minus. If only we can get our hands on the other.... :)

    As a new participant I'll "pop in" and say hello! This appears to be an intriguing site. Thanks for the opportunity...

    Casio is good for scientific calculator.
