[alogo] Inclined-node curves

a^2/x^2 + b^2/y^2 = 1

Point X moves on fixed circle c of radius a.
The tangent at X cuts the fixed line at Y.
The parallel to the tangent at X, at distance b from it, cuts the orthogonal to e at Y, at Z. As X moves, Z describes this locus.

Variable masters : c, e, y, b.
