Angle print that page

In geometry , an angle is the figure formed by two rays sharing a common endpoint , called the vertex of the angle . [ 1 ] The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one | 2011/10/1 19:00:32

Angle of view print that page


In photography , angle of view describes the angular extent of a given scene that is imaged by a camera . It is used interchangeably with the more general term field of view . It is important to distinguish the angle of view from the angle of coverage , which describes the angle of projection

Contact angle print that page


The contact angle is the angle at which a liquid / vapor interface meets a solid surface . The contact angle is specific for any given system and is determined by the interactions across the three interfaces. Most often the concept is illustrated with a small liquid droplet resting on

Northwest Angle print that page


The Northwest Angle , known simply as the Angle by locals, and coextensive with Angle Township , is a part of northern Lake of the Woods County, Minnesota , and is the only place in the United States outside Alaska that is north of the 49th parallel . That parallel is the northern boundary

Dutch angle print that page


A special Dutch Angle is the Bavarian Angle , where the camera position is changed about 90° from the common angle . Horizontal lines become vertical. A Dutch angle differs from a high angle shot and low angle shot (although Dutch angle shots are often combined with those for artistic

Degree (angle) print that page

A degree (in full, a degree of arc , arc degree , or arcdegree ), usually denoted by ° (the degree symbol ), is a measurement of plane angle , representing 1 ⁄ 360 of a full rotation ; one degree is equivalent to π/180 radians . It is not an SI unit , as the SI unit for angles is radian | 2011/8/20 17:13:30

Hour angle print that page

In astronomy and celestial navigation, the hour angle is one of the coordinates used in the equatorial coordinate system to give the position of a point on the celestial sphere . The hour angle of a point is the angle between the plane containing the Earth's axis and the zenith (the | 2011/8/3 15:05:48

Angle trisection print that page


With such tools, the task of angle trisection is generally impossible , as shown by Pierre Wantzel (1837). Wantzel's proof relies on ideas from the field of Galois theory —in particular, trisection of an angle corresponds to the solution of a certain cubic equation , which is not possible

Small-angle X-ray scattering print that page

the separation of the weak scattered intensity from the strong main beam. The smaller the desired angle , the more difficult this becomes. The problem is comparable to one encountered when trying to observe a weakly radiant object close to the sun, like the sun's corona. Only if the moon blocks | 2011/9/2 14:41:54

Pressure angle print that page


Just as there are three types of profile angles, there are also three types of corresponding pressure angles: the transverse pressure angle , the normal pressure angle , and the axial pressure angle . [ 3 ] [ edit ] See also List of gear nomenclature [ edit ] References ^ http
