Outcomes
In this lesson you will learn
- Use transformations to derive the equations of circles with centres off the origin.
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 write the equation of a circle with centre at the origin and given radius.
- Have an understanding of transformations and what effect certain transformations have on the equations of the figures involved.
- The use of mapping notation to describe transformations.
