SOURCE: solving simultaneous equation with scientific

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.

SOURCE: Inputing scientific notation into my calculator

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

SOURCE: Why does it solve in fractions?

The calculator has two Input/Output modes: the default MthIO (new) and the old LineIO.

  1. In MthIO you enter fractions and radicals as you see them in textbook (multiple levels). Calculations are exact and results are generally a mixture of fractions and radicals.
  2. In LineIO, numbers are entered the old way and all numbers, operations are written on a single line. All fractions and radicals are converted into decimals numbers.

If you use the default MthIO you can let your calculator perform the operations in exact arithmetic. When you obtain the end result, you can easily convert a fraction/radical result into a decimal one by pressing the [S<=>D] key, or press [SHIFT][=] instead of [=].

However if you do not care about the MthIO and its nifty functionalities, you can configure your calculator to use LineIO.

To set LineIO press [SHIFT][MODE][2:LineIO]

How can i write this in my calculator example. 2x=10 the answer is x=5 but how can i put x in the calculator


What you want to do is solve the linear equation 2x=10 to find the value of the unknown x that makes the equality true. Solving an equation usually involves rearranging therms, factors and so on. However your calculator was not designed to handle the solution of equations, no matter how simple they are.
Some Casio scientific calculators can solve some types of equations (polynomials of degree 2 or 3, simultaneous linear equations in up to 3 unknowns). These are the FX-115 ES (Plus) and FX-991 ES (Plus C). Other equivalent models are sold in the world under different names.

How to solve 7*3 matrices on casio scientific calculator


The enclosed screen capture shows all the possible dimensions for matrices on the Casio FX-119ES/991ES. As you can see the maximum dimension of any matrix is 3. You can only create matrices with dimensions less than or equal to 3.

How can i do algebra and keep the pronumerals and not use the inputted number? I am using the latest casio, it is a scientific calculator (not sure which model)


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.

SC-6103 aurex prestige calculator


You must have pressed the MODE key followed by SOLV , QUAD or SIMUL-2 or SIMUL-3 . If the calculator has these a programs they solve a Quadratic equation, a simultaneous system of two linear equations (SIMUL-2) . a system of 3 linear equations (SIMUL-3).

To use these solvers (IF YOU ARE INTERESTED), you select the solver you want and you will be prompted for a first coefficient (a, or a1). You enter the value and press the DATA key and you will be prompted for the next coefficient.

To exit the Solver mode press the MODE key followed by the key next to which there is DEC or >DEC. It might also be marked COMP.
Sorry, I do not have that very calculator but an other AUREX Scientific calculator (DS-752C).

Trying to get calculator to display in scientific notation


Press the [SHIFT][MODE] to access the (SETUP) screen. -See the screen capture below. Press [7:Sci] to select the output display format to be Scientific.
You will then be prompted to key in a number between 0 and 9 to choose the number of decimal digits.

If you do not want fractions nor radicals set the default Input/Output format to LineIO.
To do so press [SHIFT][MODE][2:LineIO]. After that perform the steps given above to select Scientific format for the output.
