Polar Equations of Conics Explained by Anil Neupane is a document available to read on EtoBox.

Here are the key steps to find the equation of the chord joining points P(r1, θ1) and Q(r2, θ2) on the conic: 1) Use the polar equation of the conic to write r1 and r2 in terms of θ1 and θ2: l r1 = l - e l cosθ1 and r2 = l - e l cosθ2 2) Write the slope of the chord PQ in terms of r1, r2, θ1, θ2: r2 - r1 m = tan(θ2 - θ1) = --------------- cosθ2 - cosθ1 3)
