sketching curve using equation

[montgomerys]

hi,


Im trying to sketch a curve using an equation. Its acurve which I will revolve to be part of a lens. The curve will be made up of x and y locations to make a lens profile. The equation is x=320- squareroot(102400-4y^2)


Has anyone got an idea how to do this? Thanks.

for a max y of 5:


y=5*t
x=360-sqrt(10240-(4*y*y))
z=0
