	Trigonometry?
		Trigonometry is a branch of mathematics that developed from simple mensuration (measurement of geometric quantities), geometry, and surveying.
		Trigonometry uses the fact that ratios of pairs of sides of triangles are functions of the angles.
		These formulas are useful in the solution of triangles, that is, the determination of measurements of a triangle from given data.

		Now using the _rotation property of a movie clip will return a value between 0 degrees and 180 degrees or if you are moving counter clock wise a value between 0 degrees and -180 degrees.
		By using the cos() to find the x coordinate and sin() for the y coordinate we will have the exact (x,y) coordinates for the orange circle on the circular path (light gray circle).
		The clip "center_cross_hairs" is used to reference a point or origin in the center of the movie.

	GameDev.net -- Ray Lighting: Creating realistic shadows for terrain (Site not responding. Last check: 2007-10-19)
		By using angle based theoretical sun rays the method is able to calculate the shadows shape and brightness in a realistic way.
		The brightness of the points in the shadows is calculated using a greyscale that simulates the amount of light reaching the different points.
		Using a real-time technique shadows are recalculated every frame whether or not the scene has changed.

		Simon Klügel in Analytische Trigonometrie (1770) used cosec for cosecant.
		The practice of placing the exponent beside the symbol for the trigonometric function to indicate, for example, the square of the sine of x, was used by William Jones in 1710.

	Trigonometry
		Trigonometry is the study of the relation between angles and sides within triangles.
		Using trigonometry you can find the length of an unknown side inside a right triangle if you know the length of one side and one angle.
		To do this, trigonometry uses right triangles which have equal angles and studies the relation between the length of the sides.

	Axodys » Rational Trigonometry
		Using more or less linear ideas, such as distance and angle, may be initially appealing but is ultimately inappropriate.
		Rational Trigonometry uses nonlinear units (quadrances and spreads) and is not appropriate for most science and engineering problems that rely on a linear system of measures.
		It was because their form of ‘rational trigonometry’ was nonlinear, and they needed a means to transform nonlinear measurements (chords and sines) to a linear unit (degree).

	Master Simple Math Concepts to Electrify Your ActionScript
		A lot of discussion about triangles in trigonometry is about the relationship between the sides of the triangle, the angles of the triangle, or some combination of both.
		One way of determining those values is by using an angle described by the triangle formed with x and y as two of it sides, as shown in Figure 3.
		Using modulus can reduce the amount of code you have to write (and, therefore, maintain) and it's really useful for common every day tasks.

		By looking at the triangles made by tangents to the sun, moon and earth during eclipses, Aristarchus was able to determine the sizes of these bodies and their distances from the earth.
		In this form it is used by surveyors, architects and engineers, as well as navigators and astronomers.

	Trigonometry--what it is good for?
		Using them, the project covered the country with multiple strings of triangles in the north-south and east-west directions (the areas between the strings were left for later) and it took decades to complete.
		A great deal of trigonometry is involved, but it is all done for you by the computer inside your gadget, all you need do is push the proper buttons.

	Using Trigonometry
		In this unit, students will explore the use of trigonometry to find unknown sides and angles in right-angled triangles, taking the concepts that were developed in the previous unit and looking at different ways of practising the new skills.
		It is important that good algebraic skills are used in setting out their work, and students can be encouraged to practice these individually and using cooperative logic problems in a group situation.
		Applying trigonometry to practical situations is an important aspect of this unit, and suitable practical activities involving the students going outside to take measurements using long measuring tapes and clinometers will give the students a better understanding of the wide uses of trigonometry.

		Students use methods from analytic geometry and from the geometry of complex numbers to prove trigonometric identities, including the Pythagorean identity and the formulas for trigonometric functions of the sum of two angles and multiples of an angle.
		They extend their uses of vectors to describe angles, lines, and planes, and they develop determinants as a way to calculate area and volume.
		They also use generating polynomials as a tool for representing a discrete distribution and discover several ways to calculate a line of best fit through the data.
