First, create 3 equations of the form , where a, b, c, and d are constants (integers
between – 5 and 5). For example, . Perform row operations on your system to obtain a
row-echelon form and the solution.
Go to the 3D calculator website GeoGebra: www.geogebra.org/3d?lang=pt and enter each of the equations.
After you have completed this first task, choose one of the following to complete your discussion post.
1. Reflect on what the graphs are suggesting for one equation, two equations, and three equations, and describe
your observations. Think about the equation as a function of x and y, for example, in the
example above. Geogebra automatically interprets this way, that is, like , it
isolates z in the equation.
2. What did the graphs show when you entered the second equation?
3. Give a simple description of the system
x=0
y=0
z=0
x = 0 can be seen as the constant function . Of course, you can use
GeoGebra to “observe” the system.
4. Give an example with 2 equations as simple as possible with 3 variables (at least 1 being non-linear; keeping
z to the one power on both equations) and describe the potential of GeoGebra to study nonlinear systems.
Your Discussion should be a minimum of 250 words in length and not more than 750 words.
