Which graphic calculator is best for multiple variable multiple conditional equations?
as a structural engineer, i deal with relatively simple mathematics, but with a high number of variables and assumptions during the design process.
i am looking for a handheld calculator which i can program with the different equations i use many times each day.
each equation has many variables, and many conditions. the best method of work for me is to use excel spreadsheets which i have built over the years(i use the "if" function and the "vlookup" function all the time)
i am not farmiliar with graphing calculators but am looking for a device into which i can program all these equations so i can take it with me to meetings and site visits so that i can evaluate on the spot
which graphing calculator will best suit my needs, and what programming language does it use
are there any handheld calculators which can be programmed in excel? or in MATLAB?
What else can I help you with?
Where is the unknown variable key located on a scientific calculator?
The unknown variable key on a scientific calculator is typically labeled as "x," "y," or sometimes just a letter representing the variable. It is often found near the number keys or in the function area, depending on the calculator model. Some calculators may also have specific keys for solving equations, such as "SOLVE" or "EQN." If you're unsure, consult the user manual for your specific calculator model.
How does writing equivalent equations help you solve a system of equations?
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

What is the difference between a linear quadratic and a quadratic quadratic?
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
What are linear equtions and simultanions equations?
Linear Equations are equations with variable with power 1 for eg: 5x + 7 = 0 Simultaneous Equations are two equations with more than one variable so that solving them simultaneously
How do you solve simultanious equations?
By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.
How do you solve equations that contain multiple opeations?
You undo one of the operations at a time, always with the aim of isolating the variable you want to solve for on one side.
What is the calculator button for variable?
the via button means the variable.
In order to solve the following system of equations by addition could you do before adding the equations so that one variable will be eliminated when you add them?
Yes, you can manipulate the equations before adding them to eliminate one variable. This can be done by multiplying one or both equations by a suitable coefficient so that the coefficients of one variable become opposites. Once the coefficients are aligned, you can add the equations together, resulting in the elimination of that variable, making it easier to solve for the remaining variable.
How do you solve equations on a TI-83 graphing calculator?
2nd [CATALOG], solve( , enter equation, variable and guess after the bracket, close brackets with " ) ". You can also put lower and upper bounds after the guess.
Which 5 equations are solving with 4 steps?
To solve equations effectively in four steps, consider these types: Linear Equations: Isolate the variable by adding or subtracting terms, then divide or multiply to solve. Quadratic Equations: Rearrange to standard form, factor or use the quadratic formula, simplify, and solve for the variable. Rational Equations: Clear the denominators, simplify the resulting equation, isolate the variable, and solve. Exponential Equations: Take the logarithm of both sides, isolate the variable, and simplify to find the solution. Systems of Equations: Use substitution or elimination to reduce the system, isolate one variable, and solve for it.
What do you do when you have two equations mutiply or divide?
To solve two simultaneous equations - usually two equations with the same two variables each - you can use a variety of techniques. Sometimes you can multiply one of the two equations by a constant, then add the two equations together, to get a resulting equation that has only one variable. Sometimes you can solve one of the equations for one variable, and replace this variable in the other equation. Once again, this should give you one equation with a single variable to be useful.
