62. Trigonometry Or Trig: Math An explanation YOU can understand of trigonometry, and what all these triangle and circles and waves mean. http://www4.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. Why? One loyal reader tells me this is done in honor of Pythagoras.) 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.

Home Education Resources Trigonometry The word "Trigonometry" is derived from two Greek words meaning measurement or solution of triangles. Trigonometry is a branch of mathematics that deals with the ratio between the sides of a right triangle and its angles. Trigonometry is used in surveying to determine heights and distances, in navigation to determine location and distances, and in fields like nondestructive testing for determining things such as the angle for reflection or refraction of an ultrasound wave. p radians. Trigonomic Properties There are several rules to make trigonometry easier. The first rule is the law of sines. This rule is valid for all triangles and is not restricted to right triangles. The law of sines is shown below. The second rule is the law of cosines. As for the law of sines, this rule is valid for all triangles regardless of the angles. The law of cosines can be seen below. Each triangle has six parts, three sides and three angles. If three of these are known including at least one side, the other three can be calculated using the two laws.

Rates of Growth Derivatives of Trigonometric functions UBC Calculus Online Course Notes Trigonometry: A day at the track Let's suppose we are watching a foot race and while watching the runners, our minds turn in a mathematical direction. Let's focus on one of the runners as she runs in a counter-clockwise direction about the circular track. She is wearing a blue hat as she runs at a constant speed. The picture below shows what we might see from three vantage points. We have three observers who can record her position. One is a photographer directly overhead, in the sponsor's blimp, and two others are on the ground in the bleachers at the East (E) and South (S) end of the track. The photographer in the blimp sees the picture shown above. However, the two observers on the ground see her running past, first one way and then the other. Each one of them can only see a one-dimensional view of her motion, and it might look as though she is bouncing back and forth, like a ping-pong ball. You might think that what these two ground observers are seeing is quite similar. Indeed, in many ways the picture that they see is the same, but they see it at different times. This is what we call a

Flash / AS Blend / WPF ASP.net / PHP ... About Scripting 3D in Flash by senocular Trigonometry So we've pretty much exhausted basic camera movement. It's time now to step it up a notch to camera rotation. Instead of changing position in space, this will be centered around changing the direction in which you're looking - effectively, camera rotation. For that, however, you'll need to know some trigonometry ( screams mysteriously sound in the distance ). It can get a little confusing if you don't already know it or at least the basics, so put your brain-caps on and prepare yourself because here we go. If you got trigonometry down pretty well already, you can probably skip this next part. Otherwise, I'll cover the basics of trig for those of you who may be in the dark. After all, it's a driving force for just about everything else in 3D that follows. Trigonometry (or trig) is the branch of mathematics that deals with the relationships between the sides and the angles of triangles and the calculations based on them. What do triangles have to do with rotation? Well, when ever you have, for example, some line segment rotated at an angle in 2D space, it makes a triangle with the x and y axes on which it sits (or really the axes at which it exists - this doesn't always have to be the x and y as you'll soon see when it comes to 3D).

The trigonometric functions Analysis index History Topics Index Version for printing The use of trigonometric functions arises from the early connection between mathematics and astronomy. Early work with spherical triangles was as important as plane triangles. The first work on trigonometric functions related to chords of a circle. Given a circle of fixed radius, 60 units were often used in early calculations, then the problem was to find the length of the chord subtended by a given angle. For a circle of unit radius the length of the chord subtended by the angle x was 2sin ( x /2). The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus . This makes Hipparchus the founder of trigonometry. The next Greek mathematician to produce a table of chords was Menelaus in about 100 AD. Menelaus worked in Rome producing six books of tables of chords which have been lost but his work on spherics has survived and is the earliest known work on spherical trigonometry. Menelaus proved a property of plane triangles and the corresponding spherical triangle property known the regula sex quantitatum.
