A helix, plural helixes or helices, is a type of smoothspace curve, i. It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis. Examples of helices are coil springs and the handrails of spiral staircases. A filled in helix for example, a spiral helical ramp is called a helicoid. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The word helix comes from the Greek word, twisted, curved. Helices can be either right handed or left handed. With the line of sight along the helixs axis, if a clockwise screwing motion moves the helix away from the observer, then it is called a right handed helix if towards the observer, then it is a left handed helix. Handedness or chirality is a property of the helix, not of the perspective a right handed helix cannot be turned to look like a left handed one unless it is viewed in a mirror, and vice versa. Two types of helix shown in comparison. This shows the two chiralities of helices. One is left handed and the other is right handed. Each row compares the two helices from a different perspective.

The alpha helix in biology as well as the A and B forms of DNA are also right handed helices.

Zt.png' alt='Circle Of Fifths Software' title='Circle Of Fifths Software' />The Z form of DNA is left handed. 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 conic helix may be defined as a spiral on a conic surface, with the distance to the apex an exponential function of the angle indicating direction from the axis. An example is the Corkscrew roller coaster at Cedar Point amusement park. A circular helix, i. A curve is called a general helix or cylindrical helix4 if its tangent makes a constant angle with a fixed line in space. A curve is a general helix if and only if the ratio of curvature to torsion is constant. A curve is called a slant helix if its principal normal makes a constant angle with a fixed line in space. It can be constructed by applying a transformation to the moving frame of a general helix. Some curves found in nature consist of multiple helices of different handedness joined together by transitions known as tendril perversions. Mathematical descriptionedit.

Can you see what fractions of the shapes have been shaded It is not as difficult as it first appears. Thank you Giancarlo Yes, I already downloaded and extracted with win I have tried several tracks. They work great I just recently purchased band in a box, so I. In mathematics, a helix is a curve in 3 dimensional space. The following parametrisation in Cartesian coordinates defines a particular helix,8 Perhaps the simplest equations for one isxtcost,displaystyle xtcost,ytsint,displaystyle ytsint,ztt. As the parametert increases, the point xt,yt,zt traces a right handed helix of pitch 2 or slope 1 and radius 1 about the z axis, in a right handed coordinate system. In cylindrical coordinates r, h, the same helix is parametrised by rt1,displaystyle rt1,tt,displaystyle theta tt,htt. A circular helix of radius a and slope ba or pitch 2b is described by the following parametrisation xtacost,displaystyle xtacost,ytasint,displaystyle ytasint,ztbt. Another way of mathematically constructing a helix is to plot the complex valued function exi as a function of the real number x see Eulers formula. The value of x and the real and imaginary parts of the function value give this plot three real dimensions. Except for rotations, translations, and changes of scale, all right handed helices are equivalent to the helix defined above. The equivalent left handed helix can be constructed in a number of ways, the simplest being to negate any one of the x, y or z components.

Tcdot sqrt a2b2, its curvature is aa. ExampleseditIn music, pitch space is often modeled with helices or double helices, most often extending out of a circle such as the circle of fifths, so as to represent octave equivalency.
