WebAug 27, 2024 · We first look for products v(r, θ) = R(r)Θ(θ) that satisfy Equation 12.4.1. For this function, vrr + 1 rvr + 1 r2vθθ = R ″ Θ + 1 rR ′ Θ + 1 r2RΘ ″ = 0 for all (r, θ) with r ≠ 0 if r2R ″ + rR ′ R = − Θ ″ Θ = λ, where λ is a separation constant. (Verify.) This equation is equivalent to Θ ″ + λΘ = 0 and r2R ″ + rR ′ − λR = 0.
