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.

    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.

    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.

    Why learn about trigonometric functions...?
    The trigonometric functions are very important in technical subjects like science, engineering, architecture, and even medicine. You will come across trig functions all the time and you are encouraged to learn them well!
    Example problem:
    The top of the Sydney Opera House is about 67 m above sea level. Have you ever thought about how to measure the height? See how this is done in The Right Triangle and its Applications Surveying is one of the many applications. Road makers, bridge builders and those whose job it is to get buildings in the right place all use trigonometry in their daily work. For more applications and examples of trigonometry in Interactive Mathematics, check out the many Uses of Trigonometry In this chapter we start by explaining the basic trigonometric functions using degrees radians and how they are used in trigonometry.

    Why are Distances Important?
    Distances are necessary for estimating:
    • Total energy emitted by an object (Luminosity)
    • Masses of objects from their orbital motions
    • True motions through space of stars
    • Physical sizes of objects
    The problem is that distances are very hard to measure...
    The problem of measuring distances
    Question:
    How do you measure the distance of something that is beyond the reach of your measuring instruments?
    Examples of such problems:
    • Military range finding to targets
    • Measuring distances to any astronomical object
    Answer:
    You resort to using GEOMETRY to find the distance.
    The Method of Trigonometric Parallaxes
    Nearby stars appear to move with respect to more distant background stars due to the motion of the Earth around the Sun. This apparent motion (it is not "true" motion) is called Stellar Parallax
    (Click on the image to view at full scale [Size: 7Kb]) In the picture above, the line of sight to the star in December is different than that in June, when the Earth is on the other side of its orbit. As seen from the Earth, the nearby star appears to sweep through the angle shown. Half of this angle, is the parallax
