Question

Anyone know how to find an indefinite integral on a ti 84 plus silver edition?

Answer 1

While getting ready for the ap tests, I realized I have no clue how to use my calculator for a lot of things...

Answer 3

That only shows how to graph it and I can't find a way to get an explicit formula.

Answer 4

hmm... I don't have on so i can't confirm...

try this? http://voices.yahoo.com/doing-integration-problem-ti-84-6458402.html

Answer 5

Don't forget step 1!!! :P

Step 1. Press the "on" button

Answer 6

haha thanks for step 1, but the rest only shows how to do a definite integral, not an indefinite one.

Answer 7

Let me end this fast: it's impossible.

Answer 8

Are you sure it can? From reading a few other results, it seems like you need another app for an indefinite integral.

Answer 9

Ah, okay, thanks guys... Guess it's back to searching for my Ti-89 then... (where did I put that thing...?)

Answer 10

Haha, good luck :)

Answer 11

Note that you shouldn't need any calculator for any indef integrals on the AP test...

Answer 12

Yeah, but just in case for future things (and it's kind of irritating). Thanks again!

Answer 13

Yeah, it would be helpful. Outside of test situations, http://www.wolframalpha.com/ does indef integrals

Answer 14

Might be a bit late to tell you how to do this but I found that if you put the indefinite integral into Y1 for a graph and then place as many numbers in L1(The more the better) and then go into "VARS", "Y-VARS", "FUNCTION" and select "Y1". Then use "Y1(L1)sto>L2" to find all Y values of the indefinite integral and use a regression command to give the equation for the Indefinite Integral.
EX:
\[Y1=\int\limits_{0}^{x}(3x^2)dx\]
\[L1={\left\{ -10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10 \right\}}\]
\[Y1(L1)\rightarrow L2\]
CubicReg using L1 as Xlist and L2 as Ylist
\[y=ax^3+bx^2+cx+d\]\[a=1 b=0 c=0 d=0\]
\[y=x^3\] is your answer
