81. Trigonometry Or Trig: Math An explanation YOU can understand of trigonometry, and what all these triangleand circles and waves mean. Quote of the Week (not mathrelated). http://www2.ncsu.edu/unity/lockers/users/f/felder/public/kenny/papers/trig.html

Quote of the Week (not math-related) Triangles, Circles, and Waves (oh my!) An Overview of Trigonometry 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. The Basic Idea 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.

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 gotten 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.

97. EAAE-AOL : Simple Trigonometry - Distance Towards Saturn A bit of trigonometry. In order to investigate these shadows further,we need some straight definitions. Detailed trigonometry. http://www.amtsgym-sdbg.dk/as/AOL-SAT/SATURN.HTM

This EAAE/AOL Student Project has been prize-awarded within the Danish Young Scientist Competition - and was given the CoolMath Award 2001. How to estimate Saturn's Mass and Distance. Planet Saturn. Photo : Albert Zijlstra, Astronomy On Line, Dutch 91 cm telescope, La Silla, picture processing by Troels Christensen. Click here for photocaption, software, imagefiles, etc The Basic Idea of this EAAE AOL project goes back to 1610, were Galileo applied planet shadows ("phases") in order to estimate the distance towards Venus. The combination of modern CCD - technique and the Astronomy On-Line Network allows a (first of it's kind ?) revival of this old Middle Age method. In this exercise, students may - applying simple math - measure a. Distance to Saturn. b. Diameter of the planet and its ring system. c. Mass of this huge gas-planet. As described below, the results fit with reasonable accuracy to the official values. The planet Saturn - is well known for its famous rings.These strange rings consist of ice and rocks, there has been some discussion about these rings. Computer simulations indicate these rings should not be stable on a geological timescale, so their existence is still an open topic The interesting point about Saturn right now is the ring-shadow, which we see marked on the picture below:
