Trigonometry is a fascinating tool, initially conceived from chords in a Unit-Circle it has wide applications and it can be said that whenever space is involved trigonometry is used irrespective of the area of interest. Etymology of the word Trigonometry comes from Greek meaning Three Angle Measure (Treis = three, Gonia = angle and Metron = measure). It is known mostly as the stuff which had weird stuff like Sine, Cosine, Tangent and Cotangent. There are basically ratios of sided of a right triangle for High school and can be summation of Series in advanced college Math. Trigonometry In Greek 'Trigonon' means a triangle. 'Metron' means a measure. The combination of these two words gives us the word 'Trigonometry'. Trigonometry is the branch of mathematics that deals with the relations between the sides and angles of triangles. In our study we will deal with the right angled triangles only. Trigonometrical Identities The trigonometric ratio's are: Sine, Cosine, Tangent, Cotangent, Secant, and Cosecant. Trigonometric Tables Trigonometric tables are used (1). to find the value of a t-ratio when the angle is given. (2). to find the angle when the value of the t-ratio is given.

  • Introduction
    In this article I will review what we both know very well, as I recently have done, trying for utility as well as conciseness. For trigonometry to be fun, one should be prepared in geometry and algebra, at least in the properties of triangles, circles and parallels, and in the manipulation of algebraic formulas. This is not really much preparation, but it is essential. The trigonometry text itself introduced the student to logarithms, once the invariable accompaniment to trigonometry, but now much less important that electronic pocket calculators are available. In omitting logarithms in trigonometry, it should be kept in view that logarithms are very important in mathematics, and the proper and efficient use of tables is still a valuable skill. These subjects belong somewhere, even if not in trigonometry. Now, come review with me!
    Trigonometric Functions
    Trigonometric functions are also called circular functions because of their simple relation to various lengths defined by a radius of a circle making an angle with a reference direction, as shown in the figure at the right. This is not the only way of defining trigonometric functions; they can be defined as analytic functions of a complex variable z by power series, for example.

    (M-7) TrigonometryWhat it is good for?
    The basic problem of trigonometry runs somewhat like this: You stand next to a wide river and need to know the distance across itsay to a tree on the other shore, marked on the drawing here by the letter C (for simplicity, let's ignore the 3rd dimension). How can this be done without actually crossing the river? The usual prescription is as follows. Stick two poles in the ground at points A and B, and with a tape measure or surveyor's chain measure the distance c between them ("the baseline"). An old surveyor's tele-
    scope (theodolite). Then remove the pole at A and replace it with a surveyor's telescope like the one shown here ("theodolite"), having a plate divided into 360 degrees, marking the direction ("azimuth") in which the telescope is pointing. Sighting the telescope, first at the tree and then at pole B, you measure the angle A of the triangle ABC, equal to the difference between the numbers you have read from the azimuth plate.. Replace the pole, take your scope to point B and measure the angle B in the same way. The length c of the baseline, and the two angles A and B, contain all there is to know about the triangle ABCenough, for instance, to construct a triangle of the same size and shape on some convenient open field.

    Right Angled Triangles
    Consider the right-angled triangle shown in the diagram. a b and c are the sides; f is the angle. This is a Greek letter and is pronounced phi . The angle between sides a and b is o , a right-angle . The side c , which is opposite the right angle, is called the hypotenuse (from a Greek word meaning stretch Pythagoras (c582 BC - c497 BC) proved what is now called Pythagoras' Theorem although it had been in use for centuries in the ancient world for building and measuring. The theorem can be described as follows: In a right-angles triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. This is written mathematically as a + b = c If a right-angled triangle has smaller sides of length 3 and 4. What is the length of the hypotenuse? From Pythagoras' Theorem

    Easily review trigonometry as you work at a computer! Note: in many places, I will mention algebraic identities. For serious students who are either algebra-deficient or have to use the material under time pressure, I highly recommend working through "all of the plausible forms" and memorizing them. This usually means algebraic isolation of various variables in the equations, and figuring out how to use multiple equations in one problem. Currently, I am not providing the homework that is required to learn the material. I would like to partially remedy this deficiency.

    Trigonometry and Music
    Sounds are produced by things that vibrate. Pure tones, like the the sounds produced by tuning forks, are described by sine waves y = A sin(2 pi f t), where t is time, f is how many times the thing is vibrating per second (f is for frequency , and A is how loud the sound is (A is for amplitude). If something is vibrating 256 times a second, you hear middle c. Sound of middle c (.wav file) Here is the graph. You can see that there are about, well, 25.6 waves during one tenth of a second. If we show you one second in the same amount of space, it just looks like a blob. If we double the frequency of any tone, we go up exactly one octave. So 512 vibrations per second is c above middle c. C above middle c (.wav file) Here is the graph. We get more complex sounds by adding waves of different frequencies and loudnesses together. A violin string or an oboe cavity will vibrate with more than one frequency at once, usually at multiples of a fundamental frequency. Here is a wave with components at 512 Hertz, 1024 Hz, 1536 Hz and 2048 Hz (1 Hz = 1 vibration per second). Sound of this wave The higher components are called harmonics of the fundamental tone. If the fundamental is c at 512 Hertz, then the second harmonic is twice the frequency, c an octave higher at 1024 Hertz, the third harmonic is g at 1536 Hertz, and the fourth harmonic is c at 2048 Hertz. A musical tone consists of the fundamental and many harmonics added together.
