Wataru. Oct 9, 2014. A polar equation of the form r = r(θ) can be converted into a pair of parametric equations. {x(θ) = r(θ)cosθ y(θ) = r(θ)sinθ. The slope m of the tangent line at θ = θ0 can be expressed as. m = dy dx ∣θ=θ0 = dy dθ∣∣θ=θ0 dx dθ ∣∣θ=θ0 = y'(θ0) x'(θ0). I hope that this was helpful. Answer link.
