Y so easy ?

x²/r + y = r

now this an equation of Parabola!!

LOL ;)

:D

what about this

just kidding!!!![3][4]

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
