A conic helix, also known as a conic spiral, may be defined as a spiralon a conic surface, with the distance to the apex an exponential function of the angle indicating direction from the axis. A curve is called a general helixor cylindrical helix[4]if its tangent makes a constant angle with a fixed line in space. See more A helix is a shape like a corkscrew or spiral staircase. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, … See more An example of double helix in molecular biology is the nucleic acid double helix. An example of conic helix is the Corkscrew roller coaster at See more • Alpha helix • Arc spring • Boerdijk–Coxeter helix • Circular polarization See more The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. A circular helix (i.e. … See more In mathematics, a helix is a curve in 3-dimensional space.
