Question
Given a circle with centre (a, b) and radius r, what are its parametric equations?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The notes state the parametric equations as x = -g + r cos θ and y = -f + r sin θ. Since the centre is (a, b) = (-g, -f), this is equivalent to x = a + r cos θ, y = b + r sin θ.
Hint
The notes provide the form using the centre (-g, -f), which is equivalent to (a, b).
