Pandrosion for 𝑝-th Roots

A Geometric Iteration and Its Residual Fingerprint A proportional-means construction associated with the old problem of doubling the cube leads to a simple fixed-point map for the equation z^p=x

From Proportional Rectangles to Sampled Analog Root Computation

We study a modern proportional-rectangle construction for positive integer-degree roots andits translation into a sampled analog computing architecture. A fixed support realizes reciprocal Newtoniteration. Replacing it by a moving line through a constructible anchor gives.
