The axis of a cone is the straight line passing through the apex about which the cone has a circular symmetry. In common usage in elementary geometry, cones are assumed to be right circular, i.e., with a circle base perpendicular to the axis. [1] If the cone is right circular the intersection of a plane with the lateral surface is a conic section.
A subset of a vector space over an ordered field is a cone (or sometimes called a linear cone) if for each in and positive scalar in , the product is in . [2] Note that some authors define cone with the scalar ranging over all non-negative scalars (rather than all positive scalars, which does not include 0). [3]
The area of an annulus is the difference in the areas of the larger circle of radius R and the smaller one of radius r: = = = (+) (). As a corollary of the chord formula, the area bounded by the circumcircle and incircle of every unit convex regular polygon is π /4
A right circular hollow cylinder (or cylindrical shell) is a three-dimensional region bounded by two right circular cylinders having the same axis and two parallel annular bases perpendicular to the cylinders' common axis, as in the diagram. Let the height be h, internal radius r, and external radius R.
Circular dichroism (CD) is the differential absorption of left- and right-handed circularly polarized light. Circular dichroism is the basis of a form of spectroscopy that can be used to determine the optical isomerism and secondary structure of molecules. In general, this phenomenon will be exhibited in absorption bands of any optically active ...
The Southern Cone (Spanish: Cono Sur, Portuguese: Cone Sul) is a geographical and cultural subregion composed of the southernmost areas of South America, mostly south of the Tropic of Capricorn. Traditionally, it covers Argentina, Chile, and Uruguay, bounded on the west by the Pacific Ocean and on the east by the Atlantic Ocean.
Con Tan Pocos Años (English: With so few years) is the second album from Mexican pop music singer and actress Lucerito. It was released on 1984. It was released on 1984. The first single was "Música", which was the song that she chose to be on OTI.
The Cono Norte (recently being called Lima Norte) is one of the five areas that make up the Lima Metropolitan Area. It is located in the northern part of the metropolis, hence its name. It is located in the northern part of the metropolis, hence its name.
