Unit Circle Symmetry: a GeoGebraBook Exploration

Nine GeoGebra applets that help students explore how symmetries about the x-axis, y-axis, and origin on the unit circle are useful in trigonometry. Examples using the sine and cosine functions are included.

Interactive Graphs for Exponential and Logarithmic Functions

A few more interactive GeoGebra applets have been added to my collection. Each of these graphs the function indicated in the name, with parameters that you can adjust using sliders. As you move a slider, you can watch how that parameter affects the graph of the function, and see what the resulting function definition looks…… Continue reading Interactive Graphs for Exponential and Logarithmic Functions

GeoGebra Applets That Help Understand Equation Behavior

A list of GeoGebra applets that help students better understand the relationship between the coefficients in an equation and the corresponding graph.

Analyzing Linear Equations: a summary

Explanation of key linear equation concepts: slope, intercepts, and equation forms. Discussion of how slope-intercept form, point-slope form, and standard form are related to one another. Includes general descriptions of the various starting points a student is likely to encounter in problems, and how to proceed from there.
