Students learn how to apply Pythagoras' Theorem to plot and derive the equation of circles on Cartesian axes.
Later, they use graphs to solve quadratic and linear equations simultaneously as learning progresses.
Differentiated Learning Objectives
- All students should be able to recognise the equation of a circle in form x2>+ y2 = r2.
- Most students should be able to plot the equation of a circle.
- Some students should be able to use the equation of a circle to solve simultaneous equations graphically.
