    What is Trigonometry?
    Trigonometry is the branch of mathematics that deals with triangle s, circle s, oscillations and waves ; it is absolutely crucial to much of geometry and physics . You will often hear it described as if it was all about triangles, but it is a lot more interesting than that. For one thing, it works with all angles, not just triangles. For another, it describes the behaviour of waves and resonance , which are at the root of how matter works at the most fundamental level . They are behind how sound and light move, and there are reasons to suspect they are involved in our perception of beauty and other facets of how our minds work - 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.
    Trickier concepts appear under expandable headings like this.
    This piece is designed as an easy introduction to trigonometry, relying on as little mathematical knowledge as possible. For topics which will be difficult without any knowledge of algebra and so on, you should see collapsible headers with dashed outlines, which expand when clicked. Feel free to skip these parts, but do delve into them if you are interested. 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

Trigonometry defines the trigonometric functions , which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century B.C. as a branch of geometry used extensively for astronomical studies. Trigonometry is usually taught in middle and secondary schools either as a separate course or as part of a precalculus curriculum. It has applications in both

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 "

The function values depend on the measure of the angle. The functions are outlined below. sine x = (side opposite x )/hypotenuse cosine x = (side adjacent x )/hypotenuse tangent x = (side opposite x )/(side adjacent x In the figure below, sin A = a/c, cosine A = b/c, and tangent A = a/b. There are two special triangles you need to know, 45-45-90 and 30-60-90 triangles. They are depicted in the figures below. The figures show how to find the side lengths of those types of triangles. Besides knowing how to find the length of any given side of the special triangles, you need to know their trig. ratio values (they are always the same, no matter the size of the triangle because the trig. ratios depend on the measure of the angle). A table of these values is given below.

    People have ask so here it is: download it! (this file includes fla's and all, just drop index.htm in a browser) PURPOSE: This is a look at trigonometry for practical use in flash actionscript. I am one of those people who could have cared less about trigonometry when it was taught to me in high school. Today I am kicking myself for not paying more attention in math class. WHY: The reason for this refresher is for the purpose of writing/programming actionscript in flash that will fake 3D in a 2D space. This was written for my own notes, but I decided someone else out there might get some use out of it. WARNING: The trigonometry is a review for any one with some common sense and the desire to learn. I do however expect the readers of this material to be knowledgeable about actionscript programming techniques when it comes to writing code for flash. With that said. Expect very little explanation about flash and the code itself. However anyone who considers themselves a flash actionscript guru should be fine. Time for a reality check yet? (You need math to understand trigonometry! You need Colin Moock's book on actionscript to understand scripting techniques in flash.) Last word, reader be ware I am not a writer and this was not written for the the purpose of regenerating these ideas in flash. Think of this material as just a tutorial on the concept of trigonometry and flash, an overview really. Ya, I know. This stuff is not new and for the most part I am just rehashing what I've read in books, examples and all. So don't go thinking I am some super smart guy. The reality is I just read a lot of books. And the people who wrote those books are just people who read a lot of books. And the people who wrote those books are, well, you get the idea. Credit will be giveing to those books at the bottom of this page.

    From LoveToKnow 1911
    TRIGONOMETRY (from Gr. rpiywvov, a triangle /2 Tpov, measure), the branch of mathematics analogy frequently called spheroidal trigonometry. Every new class of surfaces which may be considered would have in this extended sense a trigonometry of its own, which would consist in an investigation of the nature and properties of the functions necessary for the measurement of the sides and angles of triangles bounded by geodesics drawn on such surfaces. History Trigonometry, in its essential form of showing how to deduce the values of the angles and sides of a triangle when other angles and sides are given, is an invention of the Greeks. It found its origin in the computations demanded for the reduction of astronomical observations and in other problems connected with astronomical science; and since spherical triangles specially occur, it happened that spherical trigonometry was developed before the simpler plane trigonometry. Certain theorems were invented and utilized by Hipparchus , but material progress was not recorded until Ptolemy collated, amended and developed the work of his predecessors. In book xi. of the

    Definitions and basics
    Trigonometric circle and angles
    Take an x-axis and an y-axis (orthonormal) and let O be the origin.
    A circle centered in O and with radius = 1, is called a trigonometric circle or unit circle.
    Turning counterclockwise is the positive orientation in trigonometry.
    Angles are measured starting from the x-axis.
    Two units to measure an angle are degrees and radians
    An orthogonal angle = 90 degrees = pi/2 radians
    In this theory we use mainly radians. With each real number t corresponds just one angle, and just one point P on the unit circle, when we start measuring on the x-axis. We call that point the image point of t. Examples:
    • with pi/6 corresponds the angle t and point P on the circle.
    • with -pi/2 corresponds the angle u and point Q on the circle.
    Trigonometric numbers of a real number t
    With t radians corresponds exactly one point p on the unit circle.
