This allows you to graph equation of the form ax^2+by^2=c. I made this to get me to get familiar with if statements in GeoGebra. Note the geometric definition (i.e. the sum or difference of the distances to the two foci from a point on the conic staying constant) Click move the sliders to adjust the conic. Click on the click box to change conics. Move point A around. Click the play button in the lower left to animate. Click the arrows button in the upper right to reset.
