Y so easy ?
x2/r + y = r
now this an equation of Parabola!!

OK, dis is purely accidental...(yet a gud one)
x=rcos@
y=rsin2@
(when i saw the question on the main page, i saw the 2 as the numeral of the @ and not as the ower LOL) now do this...
i know its jus moderate...not dat difficult trust me...try it out..

y = 2rsin@cos@
x = rsin@
Sin@ = x/r
Cos@ = [1/r]√(r2-x2)
y = 2x*√(r2-x2)/r
y2r2/4x2 = r2 - x 2
y2r2 = 4x2r2 - 4x4
This is a polynominal of degree 4
Replce x2 = a
It forms a quadratic solve it and it can be plot easily
