Curve

In mathematics, a curve (also called a curved line in older texts) is, generally speaking, an object similar to a line but that need not be straight. Thus, a line is a special case of curve null curvature.

Various disciplines within mathematics have given the term different meanings depending on the area of study, so the precise meaning depends on context. However, many of these meanings are special instances of the definition which follows. A curve is a topological space which is locally homeomorphic to a line. In everyday language, this means that a curve is a set of points which, near each of its points, looks like a line, up to a deformation. A simple example of a curve is the parabola, shown to the right. A large number of other curves have been studied in multiple mathematical fields.

A closed curve is a curve that forms a path whose starting point is also its ending point—that is, a path from any of its points to the same point.

Closely related meanings include the graph of a function (as in Phillips curve) and a two-dimensional graph.

French curve

A French curve is a template usually made from metal, wood or plastic composed of many different curves. It is used in manual drafting to draw smooth curves of varying radii. The shapes are segments of the Euler spiral or clothoid curve. The curve is placed on the drawing material, and a pencil, knife or other implement is traced around its curves to produce the desired result.

Modern successors

Modern computer-aided drafting (CAD) systems use vector-based graphics to achieve a precise radius, so no template is required. Digital computers can also be used to generate a set of coordinates that accurately describe an arbitrary curve, and the points can be connected with line segments to approximate the curve with a high degree of accuracy. Some computer-graphics systems make use of Bézier curves, which allow a curve to be bent in real time on a display screen to follow a set of coordinates, much in the way a French curve would be placed on a set of three or four points on paper.

Curve (film)

Curve is a 2016 American horror thriller film directed by Iain Softley. It stars Julianne Hough and Teddy Sears. It was produced by Jason Blum for his Blumhouse Productions banner.

Recovery (TV series)

Recovery was a music and youth-oriented television series that was broadcast by ABC TV in Australia. The show was aired each Saturday morning from 9am to 12pm, following the overnight video clip program, Rage, and was broadcast from 20 April 1996 to 29 April 2000.

Content

Each episode featured a mix of live performances, music videos, other youth-relevant pop culture segments and comedy sketches.

Personnel

Recovery was primarily hosted by Dylan Lewis, although in the earlier episodes produced in Sydney, the hosting and segment introduction duties were shared with others, such as Sarah Macdonald. Once production moved to Melbourne, the show was co-hosted by Tamara Rewse, who was replaced by Jane Gazzo, and was shot entirely before a live studio audience.

Film reviews were presented by Leigh Whannell, who expressed an appreciation of the horror genre and later co-created the Saw horror film franchise. Vince Perry judged home made versions of popular films that would be submitted weekly by viewers in a segment called Cinema Amateur. Pheona Donohoe of the Scenestar organisation presented the all-ages gig report and DJ J'Nett presented the electronic dance music segment. Actor/comedian Angus Sampson was also a regular co-host, although mainly under the guise of his mysterious alter-ego, "The Enforcer". This format would last until November 1998, whereupon Gazzo moved to the United Kingdom (UK), while Lewis pursued other interests, including his band The Brown Hornet.

Recovery (Eminem album)

Recovery is the seventh studio album by American rapper Eminem. It was released on June 18, 2010, by Shady Records, Aftermath Entertainment and Interscope Records as the follow-up to Eminem's Relapse (2009). Originally planned to be released as Relapse 2, the album was renamed to Recovery when Eminem found the music of the new album different from its predecessor.

Production of the album took place during 2009 to 2010 at several recording studios and was handled by various record producers, including Alex da Kid, Just Blaze, Boi-1da, Jim Jonsin, DJ Khalil, Mr. Porter and Dr. Dre. Eminem also collaborated with artists such as Pink, Lil Wayne, and Rihanna for the album. Recovery featured more introspective and emotional content than its predecessor and the theme of the album revolved around his positive changes, anxiety, and emotional drives. To promote the album, he performed the album's songs live on televised shows, at awards ceremonies, musical events and also headed The Recovery Tour. It spawned four singles; "Not Afraid", "Love the Way You Lie", "No Love" and "Space Bound" with the former two both reaching number one on the Billboard Hot 100.
