👉 Cycloidally means that a curve is an oblique ellipse, or more specifically, a cycloid. In other words, it's a type of curve where the angle between two curves (lines) on the same plane is constant and the distance between them is proportional to the arc length.
This term has been used historically in mathematics, physics, and engineering to describe a curved shape that represents an ellipse with a twist or bend. It's often seen in geometric optics, particularly when studying the
