MPM2D Equation of a Circle – 2015-11-02

We learned about the equation of a circle today! In this course we only talk about equations of circles that have their centres at the origin, (0,0) .

Here’s a nice, short video from Al Richards in KPDSB. He uses d to represent distance, where we used |\overline{OP}| in class today.

Here’s the sheet we worked on in class, with a couple of typos fixed:

Equation of a Circle Centred at the Origin

Remember that we start review tomorrow, and we have a test on Analytic Geometry on Friday!
