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.”

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 "

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.

document.writeln(''); document.writeln('Loading...'); Username Password Remember me Forgot your password? Browse SHOP Log In Search Site: trigonometry Main the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These six trigonometric functions in relation to a right triangle are displayed in the figure . For example, the triangle contains an angle A , and the ratio of the side opposite to A and the side opposite to the right angle (the hypotenuse) is called the sine of A , or sin A ; the other trigonometry functions are defined similarly. These functions are properties of the angle A independent of the size of the triangle, and calculated values were tabulated for many angles before computers made trigonometry tables obsolete. Trigonometric functions are used in obtaining unknown angles and distances from known or measured angles in geometric figures. Trigonometry developed from a need to compute angles and distances in such fields as astronomy , map making, surveying, and artillery range finding. Problems involving angles and distances in one plane are covered in

Search Advanced Site Map A-Z Index Professional Development ... Printer-friendly version Trigonometry Grades Eight Though Twelve - Mathematics Content Standards. Trigonometry uses the techniques that students have previously learned from the study of algebra and geometry. The trigonometric functions studied are defined geometrically rather than in terms of algebraic equations. Facility with these functions as well as the ability to prove basic identities regarding them is especially important for students intending to study calculus, more advanced mathematics, physics and other sciences, and engineering in college. Students understand the notion of angle and how to measure it, in both degrees and radians. They can convert between degrees and radians. Students know the definition of sine and cosine as y- and x- coordinates of points on the unit circle and are familiar with the graphs of the sine and cosine functions. Students know the identity cos (x) + sin (x) = 1: 3.1 Students prove that this identity is equivalent to the Pythagorean theorem (i.e., students can prove this identity by using the Pythagorean theorem and, conversely, they can prove the Pythagorean theorem as a consequence of this identity).
