    An introduction to trigonometry. Turning counterclockwise is the positive orientationin trigonometry. Angles are measured starting from the xaxis.
    http://www.ping.be/~ping1339/gonio.htm
    An introduction to TRIGONOMETRY
    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.

    http://aleph0.clarku.edu/~djoyce/java/trig/what.html
    What is trigonometry?
    Trigonometry as computational geometry
    Angle measurement and tables
    If there is anything that distinguishes trigonometry from the rest of geometry, it is that trig depends on angle measurement and quantities determined by the measure of an angle. Of course, all of geometry depends on treating angles as quantities, but in the rest of geometry, angles aren't measured, they're just compared or added or subtracted. Trigonometric functions such as sine, cosine, and tangent are used in computations in trigonometry. These functions relate measurements of angles to measurements of associated straight lines as described later in this short course. Trig functions are not easy to compute like polynomials are. So much time goes into computing them in ancient times that tables were made for their values. Even with tables, using trig functions takes time because any use of a trig function involves at least one multiplication or division, and, when several digits are involved, even multiplication and division are slow. In the early 17th century computation sped up with the invention of logarithms and soon after slide rules. With the advent of calculators computation has become easy. Tables, logarithms, and slide rules aren't needed in trigonometric computations. All you have to do is enter the numbers and push a few buttons to get the answer. One of the things that used to make learning trig difficult was performing the computations. That's not a problem anymore!

    Frequently Asked Questions About Trigonometry
    Back to Dave's home page Q: What is trigonometry?
    A: Trigonometry is the study of how the sides and angles of a triangle are related to each other. Q: WHAT? That's all?
    A: Yes, that's all. It's all about triangles, and you can't get much simpler than that. Q: You mean trigonometry isn't some big, ugly monster that makes students turn green, scream, and die?
    A: No. It's just triangles. Q: Oh. But isn't that boring?
    A: We'll try to make it a little more fun by letting you play around with the triangles interactively. Let's start. Click on a topic to go to that page. If this is your first visit to these pages, we recommend that you start with the first item in the list. This material assumes that you know:
    • How to measure angles
    • That a right angle is is 90 degrees
    • The sides of a triangle: the base , the height , and the hypotenuse
    If you aren't familiar with these concepts, you'll have to ask your math teacher to assist you with them. J. David Eisenberg

      • Calculate cos(3u) in terms of cos(u)
        cos(2u+u) = cos(2u)cos(u)-sin(2u)sin(u) = (cos (u)-sin (u))cos(u)-2sin(u)cos(u)sin(u) = cos (u) - sin (u)cos(u)-2sin (u)cos(u) = cos (u) -3sin (u)cos(u) cos (u) -3cos(u)+3cos (u) 4cos (u) -3cos(u) In the same way sin(3u) = -4sin (u) -3sin(u)
      • prove that : cos(t)+sin(t) cos(2t) - = - cos(t)-sin(t) 1- sin(2t)
        cos(2t) = 1- sin(2t) cos (t)-sin (t) (cos(t)-sin(t))(cos(t)+sin(t)) - = = 1-2sin(t)cos(t) cos(t)cos(t)-2sin(t)cos(t)+sin(t)sin(t) (cos(t)-sin(t))(cos(t)+sin(t)) - = (cos(t)-sin(t))(cos(t)-sin(t)) cos(t)+sin(t) cos(t)-sin(t)
      • show that sin(p)-sin(q) p+q = cot(-) cos(q)-cos(p) 2
        sin(p)-sin(q) = cos(q)-cos(p) 2cos((p+q)/2)sin((p-q)/2) = -2sin((p+q)/2)sin((q-p)/2) cos((p+q)/2) = sin((p+q)/2) p+q cot(-) 2

    Trigonometry and Right Triangles Introduction Trigonometry Mathematics Contents ... Home First of all, think of a trigonometry function as you would any general function. That is, a value goes in and a value comes out. If that does not seem quite clear, go see The Definition of a Function and What is f(x)? The names of the three primary trigonometry functions are: sine cosine tangent These are abbreviated this way: sine.....sin cosine.....cos tangent.....tan So, instead of writing f(x) , we will write: sin(x) cos(x) tan(x) Often, in general mathematics notation the parentheses are dropped from the above examples. Therefore, the notation will often look like this: sin x cos x tan x In Zona Land we will keep the parentheses. Now, as usual, the input value is x. This input value usually represents an angle. For the sine function, when the input value is 30 degrees, the output value is 0.5. We would write that statement this way: Below is a listing of several popular input and output values for the three main trigonometry functions. You do not have work at memorizing this table. After you use trigonometry for a while, these values will be remembered quite easily. At this point our central issues will revolve around these questions: Where do these numbers come from?

    TRIGONOMETRY
    During this tutorial you will be asked to perform calculations involving trigonometric functiions. You will need a calulator to proceed.
    Panel 1 The purpose of this tutorial is to review with you the elementary properties of the trigonometric functions. Facility with this subject is essential to success in all branches of science, and you are strongly urged to review and practice the concepts presented here until they are mastered. Let us consider the right-angle triangle shown in Panel 1. The angle at C is a right angle and the angle at A we will call q . The lengths of the sides of the triangle we will denote as p, q and r. From your elementary geometry, you know several things about this triangle. For example, you know the Pythagorean relation,
    hypotenuse , is equal to the sum of the squares of the lengths of the other two sides. We know other things. For example, we know that if the lengths of the three sides of any triangle p, q and r are specified, then the whole triangle is determined, angles included. If you think about this for a moment, you will see it is correct. If I give you three sticks of fixed length and told you to lay them down in a triangle, there's only one triangle which you could make. What we would like to have is a way of relating the angles in the triangle, say q , to the lengths of the sides.
