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.
Angle Measures
Exploration of ways of measure the size of an angle: fraction of a circle, degrees, or radians. How to convert between differing measures of the same angle. Includes some reasons why 360 degrees is a convenient measure of a full circle.
Function Translations: How to recognize and analyze them
How to determine both vertical and horizontal translation factors (relative to a “parent function”) when looking the definition of a function.
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.
