Unit 5 Geometric & Algebraic Connections
Circles:
Using the above link, what do you notice about a, b, and c?
Using the above link, what happens to the circle when you adjust h? ...adjust k? ....adjust r?
Can you guess what h, k and r will do as you enter different values in one of the four circle formats provided?
Using Khan Academy's explanation, how does the circle equation 'simplify' when the equation is at the origin or (0, 0) is the center of the circle?
