निम्नलिखित वृत्तों के प्रचलिक समीकरण ज्ञात कीजिए- (i) `3x^(2)+3y^(2)=4` (ii) `x^(2)+y^(2)+px+py=0`

Answer» Correct Answer - (i) `x=2/sqrt(3) cos theta, y=2/sqrt(3) sin theta;` (ii) `x=(-p)/2+p/sqrt(2) cos theta, y=(-p)/2+p/sqrt(2) sin theta`
(i) `3x^(2)+3y^(2)=4" "implies " "x^(2)+y^(2)=(2/sqrt(3))^(2) implies a=2/sqrt(3)`
अब, `x=a cos theta, y=a sin theta, 0 le theta le 2pi`
`implies x=2/sqrt(3) cos theta, y=2/sqrt(3) sin theta, 0 le theta le 2pi`
