Question about Texas Instruments TI-83 Plus Calculator

Ad

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.

Google translated the heading of you question as **Referenc(es)**ing** algebraic variables.**

Some Scientific calculators have a few memory locations called a, b, c, d, M, x and y. M is the continuous memory while the others are variables where you can store values in view of some future calculations. These are usually accessed with** STO> key + Letter **name to store the values and **RCL + letter name** to recall the values to the command line. The values are fixed to 0 by default or to the last values stored in the named memory locations. **However the calculators do not handle algebra, unless they have a COMPUTER ALGEBRA SYSTEM or CAS.** Only some graphing calculators have that capability.

The Calculator does not have a Computer Algebra System (CAS), and cannot perform algebraic operations with variables. However if you enter some expression with variables, it can solve for one unknown after it prompts you for the values of the others

This calculator cannot manipulate algebraic expressions. You can enter an expression and generate a table of values. You can enter an equation in one unknown and solve it. But you cannot do algebra.

You would need a calculator that has a Computer Algebra System (Algebra FX 2.0, or ClassPad 300/330). Sorry.

Factoring is one of the hardest problems of elementary algebra. Not all calculators are designed to handle it. To be able to factor on a calculator, the calculator must have a COMPUTER ALGEBRA SYSTEM. Some expensive calculators have that feature. Most calculators (scientific ones) do not have a CAS.

Consult an elementary (beginning) algebra texbook to read on and understand factoring. For homework it is more efficient to use standard techniques or a combination of techniques to factor polynomials.

In answering your other question I did make a mistake: I looked at the wrong version of the manual. The Algebra FX 2 Plus does solve for eigenvalues. Under the CAS. Here is a screen capture to help you.

I am somewhat puzzled at your affirmation concerning factoring and expanding algebraic expressions. The TINspire does not do symbolic algebra, only the TI Nspire CAS does.

If you have the TINspire CAS, (version 2.x) you can

If you have the TINspire CAS, (version 2.x) you can

- press the HOME button, then select A:Calculate.
- In one of the pages, press MENU.
- Select [3:Algebra]
- Use Down Arrow or enter the number 2:Factor, or 3:expand
- In the command line, expand( , complete the command by entering the expression, close the right parenthesis and press [ENTER].
- The calculator should give you the expanded result.

It is always risky to try to answer a question about a calculator of an undisclosed model.

To be able to symbolic algebra (with variables), one needs a calculator with CAS (or Computer Algebra System). These types of calculators are special graphing calculators. ( Not all graphing calculators have a CAS.)

To get back to your question: No, you cannot do algebra with a mere scientific calculator even a recent one. All you can do is define an equation with variables A,B,C,D, Y and X and press the Solve button if it exists. The calculator will ask: Solve for X?. If you say yes, you will be prompted for the values of all letters (A,B,C,D, Y) in your equation and the calculator will search for the value of X, that makes the left side of your equation equal to the right side.

It will display the X-value and the difference L-R.

Hi,

If I understand correctly you want to perform matrix calculations on matrices the coefficients of which may be numbers and/or letters (variables, parameters). While you can calculate on numerical matrices, you cannot do so with matrices with non numerical coefficients. this calculator does not know symbolic algebra.

For symbolic algebra and calculus you would need a calculator with a CAS, Computer Algebra System. Exemples of those are the TI89, Ti92, Ti Voyage 200 PLT, The Casio FX-Algebra, the Casio ClassPad, HP48S/X/G/GX/G+, HP49G/49G+, HP50G, HP48GII etc.

Hope it Helps.

Hello,

There is a function to calculate them for you.

In CAS, or Algebra or Tutor Modes, use the x! option

In Run-Math, press [OPTN][F6] to pan right, then [F1] to access the (PROB) menu then enter option number corresponding to x!

The way it works is as follows

number ! [EXE].

Due to memory limitations, you can calculate factorials of numbers up to 69.

Hope it helps.

What is the question? If you mean symbolic algebra with a, c, x,y, z, this calculator does not do it natively. You might however find additional programs on the Internet that can do some form or another of symbolic algebra. If you really need help, maybe a more detailed formulation of your request will help us help you.
