Outcomes

In this lesson you will

• Rewrite the general and standard forms of the equation of a circle in transformational form.
• Use the transformational form to gain information about, and help with the graphing of, the circle.

By the end of this section you should be able to:

• Analyze and translate between symbolic, graphic, and written representations of circles and ellipses.
• Translate between different forms of equations of circles and ellipses.
• Write proofs using various axiomatic systems and assess the validity of deductive arguments.
• Write the equations of circles and ellipses in transformational form and as mapping rules to visualize and sketch graphs.
• Demonstrate an understanding of the transformational relationship between a circle and an ellipse.
• Apply properties of circles.
• Solve problems involving the equations and characteristics of circles and ellipses.

Prerequisites

To be successful in this lesson, it would be helpful to know the following:

• How to rewrite the equations of other functions in transformation form.
• How to use various transformations like stretching and sliding to obtain the graph of a given equation from some standard position of the equation.
