Tangents are drawn from a curve (shown in red). A line from a fixed point intersects the tangent perpendicularly at another point. The Pedal curve i...



A line is drawn through a fixed point and a point on a curve. The conchoid is the locus of two points on the line and on opposite sides of the curve ...
