Disc integration, also known in integral calculus as the disc method, is a method for calculating the volume of a solid of revolution of a solid-state material when integrating along an axis "parallel" to the axis of revolution. This method models the resulting three-dimensional shape as a stack of an infinite number of discs of varying radius ...
The 3rd part i.e., cued as step usually uses half the time of the whole pattern, e.g. one quarter note The tri-ple part may be danced evenly, e.g., two eighth notes or unevenly (on swung notes), e.g., the first part taking up 2/3s of a beat and the second part 1/3, or the first part taking up 3/4 of the beat and the 2nd part 1/4.
The samba line dance is an example of a two-wall dance. While doing the "volte" step, the dancers turn 180 degrees to face a new wall. [citation needed] In a four-wall dance, the direction faced at the end of the sequence is 90 degrees to the right or left from the direction in which they faced at the beginning (quarter turn). As a result, the ...
Rudolf Laban presenting his notation system, circa 1929 Dance workshop based on Laban's notation system, circa 1929. Labanotation (grammatically correct form "Labannotation" or "Laban notation" is uncommon) is a system for analyzing and recording human movement (notation system), invented by Austro-Hungarian choreographer and dancer Rudolf von Laban (1879–1958, a central figure in European ...
In Stepanov notation, downturns can be written in terms of numbers, putting the different numbers of turns in the same order and pattern the dancer executes them. For example, if the numbers 1, 2, and 3 were written in a straight line, then the dancer would similarly turn three times in a straight line.
An annulus Illustration of Mamikon's visual calculus method showing that the areas of two annuli with the same chord length are the same regardless of inner and outer radii. [1] In mathematics, an annulus (pl.: annuli or annuluses) is the region between two concentric circles. Informally, it is shaped like a ring or a hardware washer.
It is common practice in diagrams to draw a line under the lead end to assist in understanding the method. Most methods have a plain course consisting of a number of leads where the pattern is the same, but different bells are in differing places. In the diagram given, the number 4 bell rings the same pattern as the number 2, but one lead earlier.
Ice dance, a discipline of figure skating, has required elements that make up a well-balanced rhythm dance program and free dance program, which must be performed during competitions. They include: the dance lift , the dance spin , the step sequence , turn sequences (which include twizzles and one-foot turns sequences), and choreographic elements.
