Find the hidden conic section.

We want our students to make connections between certain relationships that exist among the coefficients of the equation of a conic section and the type of conic section that results. This GeoGebra worksheet can be use to generate numerous examples of different conic sections quickly.  When the graph is displayed, students can see how the graph changes dynamically in response to the changing coefficients.  When the graph is turned off, students can be challenged to predict the type of conic section that will result.  Then, they can test their prediction and search for the conic section by moving the point A to reveal the graph in yellow.
