Trigonometric functions

In mathematics, the trigonometric functions (also called the circular functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.

The most familiar trigonometric functions are the sine, cosine, and tangent. In the context of the standard unit circle (a circle with radius 1 unit), where a triangle is formed by a ray originating at the origin and making some angle with the x-axis, the sine of the angle gives the length of the y-component (the opposite to the angle or the rise) of the triangle, the cosine gives the length of the x-component (the adjacent of the angle or the run), and the tangent function gives the slope (y-component divided by the x-component). More precise definitions are detailed below. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle. More modern definitions express them as infinite series or as solutions of certain differential equations, allowing their extension to arbitrary positive and negative values and even to complex numbers.

Stargate SG-1 (season 4)

Season four of Stargate SG-1, an American-Canadian television series, began airing on June 30, 2000 on Showtime. The fourth season concluded after 22 episodes on February 14, 2001 on British Sky One, which overtook Showtime in mid-season. The series was developed by Brad Wright and Jonathan Glassner. Season four regular cast members include Richard Dean Anderson, Michael Shanks, Amanda Tapping, Christopher Judge, and Don S. Davis.

Production and release

In the scene in "Divide and Conquer" that flashes back to the events in Upgrades, where Carter and O'Neill are trapped on opposite sides of the forcefield, lines were written but the actors chose not to say them. In "Watergate", melted toxic wax was used to give Maybourne a frozen look. Tom McBeath couldn't breathe it in or would have risked his own health. The actual ending of the episode where O'Neill proposes that the two races had just exchanged hostages was not the intended ending, which is why the episode appears to end so abruptly. In "Beneath the Surface", Thera and Jonah were supposed to kiss to confirm that they were in a relationship, but this was dropped because O'Neill had already kissed Carter earlier in the season in "Window of Opportunity".

The serial originally ran weekly on Sunday nights on BBC One from the 4 to 25 October 2009.

Plot

For an in-depth account of the plot, see main article: Emma (novel)

Austen's classic comic novel follows the story of the "handsome, clever and rich" Emma Woodhouse. Dominating the small provincial world of Highbury, Emma believes she is a skilled matchmaker and repeatedly attempts to pair up her friends and acquaintances. Nothing delights her more than meddling in the love lives of others. But when she takes protege Harriet Smith under her wing, her interference has a detrimental effect.

Emma (song)

"Emma", also known as "Emma, Emmaline" or "Emmeline", is a song by Errol Brown and Tony Wilson released as a single by British soul band Hot Chocolate in 1974. It reached number 3 in the UK Singles Chart and number 8 in the US Billboard Hot 100 chart. After being asked by producer Mickie Most to add "depth and darkness" to his compositions, Brown wrote the song about the death of his mother.

Plot

The song details the love of the (nameless) singer and a girl called Emmaline from the age of five, through a wedding at 17 until her suicide at an unspecified later date. Emma it seems wanted to be a "movie queen" but could never find the breaks and eventually kills herself because "I just can't keep on living on dreams no more."

Cover versions

Emma (1996 TV film)

Jane Austen's Emma is an adaptation of the 1815 novel of the same name. It was adapted for the British television network ITV in 1996, directed by Diarmuid Lawrence and dramatised by Andrew Davies, the same year as Miramax's film adaptation of Emma starring Gwyneth Paltrow. This production of Emma stars Kate Beckinsale as the titular character, and also features Samantha Morton as Harriet Smith and Mark Strong as Mr. Knightley.

Davies had recently adapted another Austen novel as the successful 1995 television serial Pride and Prejudice for BBC when he proposed to adapt the novel Emma for the network. BBC had already made such an agreement with another screenwriter however, leading Davies to approach ITV.

Emma received generally positive reviews from critics, who believed it to be superior to the 1996 Miramax film. Most focused on Beckinsale's performance as a positive highlight. It aired on ITV in November 24 1996 and garnered an estimated 12 million viewers. It also was broadcast on the American channel A&E in February 16 1997.
