Circles and Equations is a powerful learning aid that combines interactive Coaching Calculators and Guides to help students master finding the center and radius of a circle by completing the square.    Work with the Coaching Calculator to find the centre and radius of a circle step by step,    - Taking constant term to right hand side  - Grouping x-related and y-related terms  - Completing the squares  - Writing in center-radius form    or go straight to a particular step.    The Guide features worked examples with circle equations where the coefficient of x is one and not equal to one.    Applications include finding the equation of a tangent line at a a given point on a circle and determining if a given point is inside a circle.    It's ideal for students as the menu design reinforces each problem solving step and examples highlight and simplify algebra that students find hard.
