The vectors from the center of the sphere to the vertices are therefore given by and Now, the angular lengths of the sides of the triangle (in radians) are then and and the actual arc lengths of the side are and Explicitly, Now make use of A B , and C to denote both the vertices themselves and the angles of the spherical triangle at these vertices, so that the dihedral angle between planes AOB and AOC is written A , the dihedral angle between planes BOC and AOB is written B , and the dihedral angle between planes BOC and AOC is written C . (These angles are sometimes instead denoted e.g., Gellert

83. Thabit

    http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Thabit.html
    
    Extractions: Thabit ibn Qurra was a native of Harran and a member of the Sabian sect. The Sabian religious sect were star worshippers from Harran often confused with the Mandaeans (as they are in [1]). Of course being worshipers of the stars meant that there was strong motivation for the study of astronomy and the sect produced many quality astronomers and mathematicians. The sect, with strong Greek connections, had in earlier times adopted Greek culture, and it was common for members to speak Greek although after the conquest of the Sabians by Islam, they became Arabic speakers. There was another language spoken in southeastern Turkey, namely Syriac, which was based on the East Aramaic dialect of Edessa. This language was Thabit ibn Qurra's native language, but he was fluent in both Greek and Arabic. Some accounts say that Thabit was a money changer as a young man. This is quite possible but some historians do not agree. Certainly he inherited a large family fortune and must have come from a family of high standing in the community.

    Extractions: by Kenny Felder Requires Fonts This sheet is meant as a guide to help you review trigonometry. I assume you're already familiar with the basic concepts, and just need to have things cleared up or refreshed; if you've never seen trig before, this sheet will probably only be helpful in conjunction with a class. Start out by considering a right triangle: that is, a triangle with one 90 o angle. The angle that we care about is one of the other ones, which we'll label with the Greek letter q . (Everyone always labels angles with Greek letters. Don't ask me why.) We're going to look at the sides: the big one, opposite the right angle, we call the hypotenuse . The other two don't have special names, but one is adjacent to q and one is opposite q , so those will do. In the triangle below, for instance, the side opposite q has length 2 (inches, or meters, or whatever). The side adjacent to q has length . The hypotenuse, therefore, must have length 4 by the Pythagorean theorem.

    Extractions: Server will be down for maintenance on 2004-06-11 from about 18:00 to 18:30 UTC. Trigonometry (Greek: "the measure of triangles") is a branch of mathematics dealing with angles triangles and trigonometric functions such as sine and cosine . It has some relationship to geometry , though people don't seem to agree on exactly what that relationship is. For some, trigonometry is just a subtopic of geometry. It has many applications: the technique of triangulation for instance is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems Two triangles are said to be similar if one can be obtained by uniformly expanding the other. This is the case if and only if their corresponding angles are equal, and it occurs for example when two triangles share an angle and the sides opposite to that angle are parallel. The crucial fact about similar triangles is that the lengths of their sides are proportionate. That is, if the longest side of a triangle is twice that of the longest side of a similar triangle, say, then the shortest side will also be twice that of the shortest side of the other triangle, and the median side will be twice that of the other triangle. Also, the ratio of the longest side to the shortest in the first triangle will be the same as the ratio of the longest side to the shortest in the other triangle. Using these facts, one defines

    Extractions: Beginnings of Trigonometry Trigonometry is an area of mathematics used for determining geometric quantities. Its name, first published in 1595 by B. Pitiscus, means "the study of trigons (triangles)" in Latin. Ancient Greek Mathematicians first used trigonometric functions with the chords of a circle. The first to publish these chords in 140 BC was Hipparchus, who is now called the founder of trigonometry. In AD 100, Menelaus, another Greek mathematician, published six lost books of tables of chords. Ptolemy, a Babylonian, also wrote a book of chords. Using chords, Ptolemy knew that sin (x + y) = sin x * cos y + cos x * sin y and a / sin A = b / sin B = c / sin C. Trigonometry has been used throughout modern and ancient history dealing with practical applications, such as surveying. Modernly, it has incorporated many other ideas instead of just triangles. The six trigonometric functions now known are sine (sin) = opposite side/ hypotenuse cosine (cos) = adjacent side/ hypotenuse tangent (tan) = opposite side/ adjacent secant (sec) = hypotenuse/ adjacent side cosecant (cosec) = hypotenuse/ opposite side cotangent (cot) = adjacent side/ opposite side Three of these ratios are the reverse of other ratios. All of these ratios are used widely to determine sides and angles of triangles. Without their discovery, surveyors and other practical mathematicians would not be able to efficiently determine relationships.
