The solution will be all points that are more than two units away from zero.">
Graphing absolute value equations and inequalities is a more complex procedure than graphing regular equations because you have to simultaneously show the positive and negative solutions. Simplify the process by splitting the equation or inequality into two separate solutions before graphing.
Some versions of Netscape require you to stop and restart your browser after installing. The files are in pdf format: Click here for the documentation on parametric curves and surfaces, including examples. Information on creating implicit and vector graphs is below.
No need to solve for z or to use parametric forms. DPGraph can plot multiple equations. The inequality is true on the "true blue" side, and false on the red side.
DPGraph added some blue to the red side, making it more magenta, to show that the inequality is true for the surface itself. Multiple simultaneous 3D inequalities are also easy.
Here's the inside of a sphere intersected with the outside of a torus: You can use the color of the surface to encode an extra dimension of information. The fractional part of the color expression is mapped to a color wheel that goes from red at 0, through magenta, blue, cyan, green, yellow, and back to red at 1.
If you'd like to display the level surfaces equipotentials, isothermals, etc. One way to make a graph move is to use DPGraph's scrollbar to slice through it in the x, y, or z directions in real time. Here's a movie of the slicer sweeping through the previous level surfaces, showing what the inside of the graph looks like.
A second way to make a graph move is to use TIME as a variable. A fourth way to make any graph move is to zoom and rotate it using the Home, Page Up, Page Down, and arrow keys. Use the up arrow key to see what's inside this bell curve contributed by Jerry Thornhill.
A sixth way to make a graph move is to make the color of the surface time-dependent. In addition to using the slicer, another way to see inside a surface is to make it transparent. This is a movie of a jellyfish head, contributed by Michael Parker. You can set DPGraph's parameters to do 2D graphs, too.
You can put as many 2D plots as you'd like into the list. Here is a snapshot from a movie of a more complicated set of 2D inequalities: While the circle pulses in and out, you can use DPGraph's scrollbar to change A, B, C, and D to vary the parameters for the sine curve and the slope of the line.
This is handy for viewing everything from complex variable conformal maps to the characteristic curves of partial differential equations. Here's a snapshot from a movie of equipotential lines "flowing" along streamlines from the source on the right to the sink on the left.
You can use DPGraph's scrollbar to adjust A the distance of the source or the sink from the origin and C the strength of the source or the sink. Another kind of 2D plot is a contour plot of a 3D graph. Red is high in elevation, blue is low.
DPGraph even lets you display 8D graphs -- here is a 3D array of time-dependent 3D vectors, using color as an extra dimension to show a pressure wave propagating through the moving vectors by setting GRAPH3D. If you would only like a few vectors instead of a whole field of them, you can use the NEAR function to select a subset of the vectors.
Ironically, because of its advanced capabilities DPGraph is excellent for demonstrating the beauty of math to beginning students.Automatic works cited and bibliography formatting for MLA, APA and Chicago/Turabian citation styles. Now supports 7th edition of MLA. A Computer Science portal for geeks.

Graphing absolute value equations and inequalities is a more complex procedure than graphing regular equations because you have to simultaneously show the positive and negative solutions.
Simplify the process by splitting the equation or inequality into two separate solutions before graphing. After we’ve mastered how to solve Absolute Value Inequalities, we are going to learn how to write an equation or inequality involving absolute value to describe a graph or statement.
Now, when solving Absolute Value Inequalities, we must never lose sight of the .
