Goals for students:
1) Identify conic sections by equation and diagram. 2) Prove that an equation or diagram is a
conic section. 3) Derive that a conic
section has been constructed by both algebraic and geometric forms. 4) Use Geometer’s Sketchpad GSP to construct
conic sections. 5) Explore applications
of the different conic sections.
