4D- Circles
Objectives:
>Identify the general equation of circles
>identify the centre (h,k) and the radius
>sketch the circle relation
>advanced: applying Complete the square method to factorise the circle relation
Task 1:
click here
explore how the values of (h,k) influences the centre of the circle
explore how the value 'r' influences the shape of the circle
Task 2:
click here
What is the centre of this circle?
what is the radius of this circle?
Can you rewrite the relation into the general circle equation?
What method could we use?
