Question about Texas Instruments TI-30XA Calculator

Hi,

You have two ways to solve an equation (not just linear) in the TI83Plus

- The solve( command the syntax of which is solve( expr, var,guess, {lower_limit, upper_limit}). Here expr is the expression (without =0), var is the variable you solve for, guess is you estimate of the solution, lower_limit and upper_limit are the bounds of the domain where you are looking for a solution. Of course your guess must be between theses limits.
- The Interactive Solver.

- The solve command is accessed through the catalog of commands [2nd][0] (CATALOG).
- Press [LN] (S) to let the cursor jump to the first command that starts with s.
- Scroll down to reach the solve( command.
- Select it and press [ENTER]. The command echoes on main screen.
- Enter the different arguments: expr, var, guess, etc.
- Close the right parenthesis and press [ENTER].
- Wait for the solution to be displayed.

Press [MATH][0:Solver]. You see what is on the first picture (I entered K-0.5*V^2). Press [ENTER]. You see what is on the right picture.

In the interactive solver you enter a value for all the parameters, constants,

Here is what I get for the small exemple I chSolving a linear equation from TI 83 - 7b60093.jpgbr />

Left -rt=0 shows that the root was found to within the calculator's tolerance.

Hope it helps.

Thank you for using FixYa.

I get the same answer. Is b wrong? When I do it in Excel I get b= -2E+06, which is -1 797 322.99 rounded to the millions, in scientific notation.

Let me know if you have any questions.

Good luck,

Paul

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

Yes, this is a form of a linear equation. Do you have a question about it?

It ia very easy to solve this linear equation. Type **solve(3*abs(x+6)=9*x-6,x)**

See captured image below

The absolutely-best, most-robust, software for solving systems of linear equations is the LINPACK software library.

It was originally written in FORTRAN.

But, see: http://www.greenecomputing.com/apps/linpack/

which indicates that a JAVA version exists.

You're trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Hello,

Let us assume you have two simultaneous linear equations :

**a_1*x+ b_1*y+c_1=0**

a_2*x +b_2*y+c_2=0

where a_1, a_2, b_1, b_2, c_1,c_2 are coefficients (numerical or algebraic).

The problem is to obtain the particular values of the unknowns x and y for which the two equations are both satisfied: If you substitute the particular values of x and y you find in any of the two equations you discover that both equalities are true.

A small system of equations like the one above can be solved by some very simple algorithms (elimination, substitution, combination) which can be carried out by hand.

The solution of large systems of linear equations can be sought by making use of the concepts of matrices (plural of matrix), determinants, and certain rules called Cramer's rules.

Due to its repetitive nature, the algorithm ( a well defined, limited sequence of steps) is suitable for a calculating machine (computer or calculator).

Certain calculators have, embedded in their ROM, a program that solves linear systems of simultaneous equations. Usually you are asked to enter the values of the coefficients a_1, etc. in a set order, then you press ENTER or EXE (Casio) . If a solution exits (not all linear systems have solutions) the calculator displays it.

Hope that satisfies your curiosity.

The tables will not say Y specifically, they only say L1, L2, L3, etc. UNLESS you type in an equation in the "Y=" button menu. When you type an equation in on that page, and then hit "2nd" "GRAPH", you will get X and Y values for that equation.

Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})

Put all of your equations right after the opening parenthesis separated by the word*and*, then a comma, then within curly braces each variable you want to solve for each separated by a comma.
