प्रश्न
Write the parametric equations of the circle:
(x − 3)2 + (y + 4)2 = 25
बेरीज
उत्तर
The equation of the circle is
(x − 3)2 + (y + 4)2 = 25
Comparing this equation with (x – h)2 + (y – k)2 = r2,
we get, h = 3, k = – 4 and r = 5
∴ the parametric representation of the circle is
x = h + r cos θ, y = k + r sin θ
i.e., x = 3 + 5 cos θ, y = – 4 + 5 sin θ.
