Trigonometry From Wikipedia, the free encyclopedia Jump to: navigation search Wikibooks has a book on the topic of Trigonometry The robotic manipulator on the International Space Station is operated by controlling the angles of its joints. Calculating the final position of the astronaut at the end of the arm requires repeated use of the trigonometric functions of those angles. All of the trigonometric functions of an angle can be constructed geometrically in terms of a unit circle centered at O Trigonometry (from Greek trigōnon "triangle" + metron "measure") is a branch of mathematics that deals with triangles , particularly those plane triangles in which one angle has 90 degrees ( right triangles ). Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions , which describe those relationships. Trigonometry has applications in both pure mathematics and in applied mathematics , where it is essential in many branches of science and technology. It is usually taught in secondary schools either as a separate course or as part of a precalculus course. Trigonometry is informally called “trig.”

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Trigonometry The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions ) comprising trigonometry are the cosecant cosine cotangent secant ... sine , and tangent . The inverses of these functions are denoted , and . Note that the notation here means inverse function not to the power The trigonometric functions are most simply defined using the unit circle . Let be an angle measured counterclockwise from the x -axis along an arc of the circle . Then is the horizontal coordinate of the arc endpoint, and is the vertical component. The ratio is defined as . As a result of this definition, the trigonometric functions are periodic with period , so where is an integer and func is a trigonometric function. A right triangle has three sides, which can be uniquely identified as the hypotenuse , adjacent to a given angle , or opposite . A helpful mnemonic for remembering the definitions of the trigonometric functions is then given by "oh, ah, o-a," "Soh, Cah, Toa," or "

11. Trigonometry A trigonometry tutorial which aims to communicate the point of trigonometry, as well as the basics of the subject with links to definitions and trig-based http://oolong.co.uk/trig.htm

by Fergus Ray Murray What is Trigonometry? Trigonometry is the branch of mathematics that deals with triangle s, circle s, oscillation s and waves ; it is absolutely crucial to much of geometry and physics . You'll often hear it described as if it was all about triangles, but I think that is missing much of the point. Waves and resonance are at the root of how matter works at the most fundamental level ; they are behind how sound and light move, and probably also how mind s and beauty work, on some level; so trigonometry turns out to be fundamental to pretty much everything. Any time you want to figure out anything to do with angle s, or turning, or swinging , there's trigonometry involved. The first thing to understand with trigonometry is why the mathematics of right-angled triangles should also be the mathematics of circles. Picture a line which can turn around one of its ends, like the hand of a clock . Obviously, the moving end of the line traces out a circle - it's like drawing with a compass . Now, consider how far this point is to the right or left of the centre point (we call this distance x ), and how far above or below (which we'll call

TRIGONOMETRY During this tutorial you will be asked to perform calculations involving trigonometric functiions. You will need a calulator to proceed. Panel 1 The purpose of this tutorial is to review with you the elementary properties of the trigonometric functions. Facility with this subject is essential to success in all branches of science, and you are strongly urged to review and practice the concepts presented here until they are mastered. Let us consider the right-angle triangle shown in Panel 1. The angle at C is a right angle and the angle at A we will call q . The lengths of the sides of the triangle we will denote as p, q and r. From your elementary geometry, you know several things about this triangle. For example, you know the Pythagorean relation, hypotenuse , is equal to the sum of the squares of the lengths of the other two sides. We know other things. For example, we know that if the lengths of the three sides of any triangle p, q and r are specified, then the whole triangle is determined, angles included. If you think about this for a moment, you will see it is correct. If I give you three sticks of fixed length and told you to lay them down in a triangle, there's only one triangle which you could make. What we would like to have is a way of relating the angles in the triangle, say q , to the lengths of the sides.
