How does the Polar Conics Calculator work?
Free Polar Conics Calculator - Given eccentricity (e), directrix (d), and angle θ, this determines the vertical and horizontal directrix polar equations.
This calculator has 3 inputs.

What 1 formula is used for the Polar Conics Calculator?

r = ed/(1 - e cos(θ))
r = ed/(1 + e cos(θ))
r = ed/(1 - e sin(θ))
r = ed/(1 + e sin(θ))
