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 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.
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 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.
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.
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.
How do you solve the system of equations when you have 4 equations with 4 unknowns?
There are several ways to do it - depending, in part, on the kind of equations. Sophisticated methods exist specifically for linear equations, among others. However, for a start, you can combine equations (1) and (2), eliminating one variable; the same for equations (2) and (3), and for equations (3) and (4) (eliminating the same variable in every case). That leaves you with 3 equations with 3 variables. Similarly, reduce the 3 equations in 3 variables, to 2 equations in 2 variables (eliminating the same variable in every case). Combine those into a single equation with 1 variable. Example for eliminating a variable: (Eq. 1) 5a + 3b - 3c + 8d = 28 (Eq. 2) 8a - 3b + 8c - 6d = 8 If you just add up the equations, you eliminate variable b. If you want to eliminate variable a, multiply the first equation by 8, and the second by (-5), then add the resulting equations.
Is an independent variable defined to be a variable that is to be predicted or estimated?
neither, an independent variable is a variable not being changed in the process of a science experiment. A variable in math cannot be described, only purpose of a variable is to take place of a number that you are trying to figure out in some equations. Others are equations with no solution.
What is a disadvantage to using equations?
Equations using multiple variables, or powers of variables, may not provide a simple numerical value for a given variable. Equations that are solvable using the quadratic formula may result in two values.
