Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

### I am not able to integration on my ti 89 titanium calculator...i mean its only solving simple ones and for the big ones like ((t+2)^(1/2))/e^t.....it completely messed up my calculus bc exam

Well it is just a calculator, it cannot do all the possible integrals you might think of. You may try to help it a bit by using the usual techniques that you were taught to transform the integral into another it might be able to find: change of variables, integration by parts. You cannot let the success on your AB or BC exam depend solely on the calculator.

### How to calculate a finite integral

Press 2ND MATH to bring up the Math menu. Select "Calculus" and then "integrate." Enter the expression, the variable of integration, the lower limit, and the upper limit, separated by commas. Close the final paren and press ENTER or diamond ENTER.

For example, to calculate the integral from 0 to pi of sin(x) dx, you want

INT(sin(x),x,0,pi)

where INT is the integral sign and pi is the lower-case Greek pi.

### Does this calculator perform integrals or derivatives?

Yes. Look in the calculus menu (2nd [CALC]). You'll find nDer, der1, and der2 for numerical differentiation and fnInt for numerical integration.

You'll find full details on these functions in the "Math, Calculus, and Test Operations" chapter of your guidebook. If you need a new guidebook, you can download it from http://www.education.ti.com

### Derivative feature does not work

The newer version of the OS 2.0.0.1188 is quite different from the initial version. It would be a good idea to upgrade the OS.
Back to your question. Since I upgraded my calculator, I am unable to illustrate the calculations with screen captures that are meaningful to you. If you do not mind I will show you how to calculate derivatives and integrals using OS Version 2.0.0.1188

In Calculator Mode
2. Use down arrow to highlight 4:Calculus or just press 4
3. Select 1:Numerical derivative at a point and press ENTER
4. An entry screen opens where you can select the name of the independent variable (default is x, not X), the point where you want the derivative and whether you calculate the first or the second derivative.
5. After you make your choices, you press ENTER and a template is displayed in calculator screen.
6. All you have to do then is to specify the function you are differentiating.
Here are a few screen captures to illustrate the process.

For the numerical integration
Select Calculus (see above)>Numerical Integration>ENTER.
Type in your integral using the template. Here is the procedure illustrated.

### How to calculate calculus problem by a scientific calculator fx-991ms

Hello,
If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

### Differentiating and Integrating Problems

Hello,
This means that you are using a non-algebraic variable in an expression. I know, I am not even paraphrasing. Exemple: if you write 2 + johnQ, where johnQ is a table of data, a picture or a GDB, graphical data base object.

Here is an exemple where mat is a 2X2 matrix and mot is a table.
Hope it helps.
