Find the parametric equations of the cirlces
(i) `x^(2)+y^(2)=1`
(ii) `x^(2)+y^(2)-4x+6y-12=0`
(iii) `4(x^(2)+y^(2))=9`
(iv) `2x^(2)+2y^(2)=7`
(v) `(x-3)^(2)+(y-4)^(2)=8^(2)`

Text Solution

Verified by Experts

The correct Answer is:
(i) `x=cos theta, y = sin theta`
(ii) `x=2+5cos theta, y=-3+5sin theta`
(iii) `x=3/2 cos theta, y=3/2 sin theta`
(iv) `x=sqrt(7/2) cos theta, y=sqrt(7/2)sin theta`
(v) `x=3+8cos theta, y=4+8sin theta`
