This software to download was designed by a teacher to help teachers teach algebra I, algebra II, trigonometry, probability and statistics, and 3D graphing. It approaches these topics from a uniquely teacher point of view. For example, it generates problems for students to solve such as systems of equations that are independent-consistent, dependent-consistent, and inconsistent.inconsistent. It generates graphs that students must identify in function notation and/or by exact formula.
3D graphing techniques are illustrated dynamically. Polar and parametric equations can be investigated with the help of a "lightning bug". Slider graphs of any functions can be created to help students visualize the effects of parameters. Piecewise-defined functions and equations that do not represent functions can be graphed. Implicitly defined equations can be graphed. Inequalities can be graphed in standared or "reversed" mode.
