  1. Hyperbolic law of cosines

    In hyperbolic geometry , the law of cosines is a pair of theorems relating the sides and angles of triangles on a Hyperbolic geometry hyperbolic plane , analogous to the planar law of cosines from plane trigonometry , or the spherical law of cosines in spherical trigonometry . Take a hyperbolic plane whose Gaussian curvature is math frac1 k 2 math . Then given a hyperbolic triangle ABC with angles &alpha , &beta , &gamma , and side lengths BC a , AC b , and AB c , the following two rules hold math cosh frac ak cosh frac bk cosh frac ck sinh frac bk sinh frac ck cos alpha, , math considering the sides, while math cos alpha cos beta cos gamma sin beta sin gamma cosh frac ak, , math for the angles. Christian Houzel page 8 indicates that the hyperbolic law of cosines implies the angle of parallelism in the case of an ideal hyperbolic triangle When &alpha 0, that is when the vertex A is rejected to infinity and the sides BA and CA are parallel , the first member equals 1 let us suppose in addition that &gamma &pi 2 so that cos &gamma 0 and sin &gamma 1. The angle at B takes a value &beta given by 1 sin &beta cosh a k this angle was later called angle of parallelism and Lobachevsky noted it by F a or &Pi a .

It presented short, humorous vignettes which ran with musical accompaniment rather than a soundtrack, and challenged panellists to guess which obscure law was being broken by the Lawbreaker character portrayed by Paul Soles , who always got arrested at the end of the vignette Robert Warner actor Robert Warner starred as the police officer . The vignettes were quite subtle, and more often than not, despite many guesses, the panellists were unable to come up with the law that was actually being broken. The vignettes alternated with depictions of actual court cases, presented in a series of still cartoons, in storyboard format, with narration. The narrator would end by asking a question about how the judge eventually ruled. The four panellists would each guess what the judge decided, and why, and each panellist would conclude by lighting up a large Yes or No in front of his or her seat. After all four panellists had guessed, the answer would be revealed. Paul Soles himself was the first show host for the initial 1971 summer episodes. Austin Willis became host from the regular 1971 fall season until the end of the series.
