There are many types of calculus problems, including differentiation and integration. Would you care to be a little more specific?

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.

That depends on what you need to do with the calculator. The TI-83 is better at some things, the TI-86 is better at some other things, and the TI-92 is better at yet other things.

The 83 and the 86 both use the Z80 processor, though the 86 is quite a bit faster. The 92 uses a 68000 processor. Though the 83 has a faster processor than the 86, the 86 has some additional calculus capabilities.

You can download TI's manuals from their support website.

There's a good comparison of present and past models here.

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.

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

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

For the numerical integration

Select Calculus (see above)>Numerical Integration>ENTER.

Type in your integral using the template. Here is the procedure illustrated.

In Calculator Mode

- Press the Menu button.
- Use down arrow to highlight 4:Calculus or just press 4
- Select 1:Numerical derivative at a point and press ENTER
- 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.
- After you make your choices, you press ENTER and a template is displayed in calculator screen.
- All you have to do then is to specify the function you are differentiating.

For the numerical integration

Select Calculus (see above)>Numerical Integration>ENTER.

Type in your integral using the template. Here is the procedure illustrated.

If you want to get an answer like 1/2X for d/dx(X^2), you will have to
purchase a CAS calculator like Casio's Algebra FX-2 or Classpad. TI series calculators also have CAS.

However, you can calculate the numerical values of derivatives and integrals only.

To calculate the value of a proper integral:

**∫**xdx from 0 to 2, input as follows:

**∫**dx(X,0,2)

To calculate derivative at a point:

SHIFT+**∫**dx key X^2,3)

Display looks like this: d/dx(X^2,3).

However, you can calculate the numerical values of derivatives and integrals only.

To calculate the value of a proper integral:

- Press the 'ON' key;
- Press the Integral key ;
- Enter your expression (example X^2+X-3 etc);
- Press the 'comma' key after your expression;
- Input the first limit after comma, input comma again after first limit;
- Close brackets;
- Press the equals key, display may return after a while with the answer.

To calculate derivative at a point:

- Press Shift and then the integration key.
- Enter your function;
- Input comma;
- input the point at which you want to evaluate the derivative;
- Close bracket and press enter.

SHIFT+

Display looks like this: d/dx(X^2,3).

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.

Hello,

Yes we can do algebra on thre TI83 Plus calculator, a lot of algebra, statistics, probabilities, graphing functions several ways, calculus(integral, differential). A lot.

If you have a particular question post it and someone will be happy to help you, and show you how to do it on your calculator.

Good luck.
