= A (\frac{d}{d θ} (5 π θ^{2} r (θ)) - \frac{d}{d θ} (4 θ^{3} r (θ)) - \frac{d}{d θ} (4 θ^{2} sin (θ) r (θ)))

\frac{d}{d θ} (5 π θ^{2} r (θ)) = 5 π (2 θ r (θ) + \frac{d}{d θ} (r (θ)) θ^{2})

\frac{d}{d θ} (4 θ^{3} r (θ)) = 4 (3 θ^{2} r (θ) + \frac{d}{d θ} (r (θ)) θ^{3})

\frac{d}{d θ} (4 θ^{2} sin (θ) r (θ)) = 4 (2 θ sin (θ) r (θ) + (cos (θ) r (θ) + \frac{d}{d θ} (r (θ)) sin (θ)) θ^{2})
