How to find indefinite integral on TI 83?

<p>question same as topic. </p>

<p>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.</p>

<p>Any help would be greatly appreciated. Thanks.</p>

2

<p>bump, does anyone know it?</p>

3

<p>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.</p>

4

<p>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. </p>

<p>Thanks!</p>

5

<p>Never mind. I found it. Thanks!</p>

6

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

7

<p>mind posting that link for me? I can't seem to find it.</p>

8

<p>it actually does not exit. Sorry!</p>

<p>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!</p>

<p>INDEFINITE integral! My Casio</a> FX-115ES Plus can do a definite integral.</p>

11

<p>haha, casio used to be the best...</p>

</p>

<p>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.</p>

13

<p>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</p>

14

<p>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. </p>

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

<p>As a new participant I’ll “pop in” and say hello! This appears to be an intriguing site. Thanks for the opportunity…</p>

<p>Casio is good for scientific calculator.</p>

17

<p>One can graph the integral of a function on a Ti 84 or 83 by doing the following:
goto Y1 and typing:
fnInt([function],X,0,X)</p>

<p>This will give you the curve for the integral which is useful for checking your integral</p>

<p>I have put a lot of thought into making a program that can find the symbolic integral. This would require porting the algorithms used in any of the major CAS programs over to Z80 assembly which would be a tiresome job but it really should not be that difficult. Anyone who is interested on this topic or would like to help me make this program please message me. A good book to get an idea how to build your own CAS is Computer Algebra and Symbolic Computation: Elementary Algorithms by Joel S. Cohen.</p>

<p>Thanks so much, seamazing! your suggestion really helped my calculus grade and I! :D</p>

<p>break it up into partial fractions.</p>

<p>You can check an indefinite integral on the TI-84 by using the Fundamental Theorem of Calculus and treating your integral and your solution as definite integrals and seeing if the results of evaluating them match. It’s explained better, here:</p>
