    3. Basic Trigonometry
    Cosine, sine and tangent are defined. The Pythagorean theorem is illustrated as well the number of degrees in a many sided figure.
    http://abe.www.ecn.purdue.edu/~agen215/trig.html
    BASIC TRIGONOMETRY
    THE RIGHT TRIANGLE
    For a triangle to be called a right triangle , one of the interior angles must be 90 degrees. The sum of the interior angles must be 180 degrees , as with all triangles.
    TRIGONOMETRIC FUNCTIONS
    PYTHAGOREAN THEOREM
    Given the length of the side opposite and the side adjacent of a right triangle, the hypotenuse can be calculated by the following formula:
    You can actually find any third side of a triangle, if the other two sides are known.
    SUM OF INTERIOR ANGLES
    If "n" is the number of vertices (corners) of a closed shape, the sum of the interior angles can be found by:
    What is the sum of the interior angles for the fourth shape above?
    Because it has four vertices, (4-2) * 180 = 360 degrees, like any four-sided shape.
    GRADE AND PERCENT GRADE
    To calculate the grade, use the following formula:
    For this example, the grade equals (25/500) = 0.05
    The percent grade equals (25/500) * 100 = 5%
    CONVERTING MAP AREA TO FIELD AREA
    If you are dealing with an area, in which the unit is square feet, or some such unit, you must square the scale of the map to calculate the proper area.
    Field Area = Map Area * (Map Scale)^2
    So if the map has a scale of 1 in. = 2000 ft., and you measure a field to have a map area of 7.0 square inches, the total area is:

    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.

    What is Trigonometry?
    Trigonometry is the branch of mathematics that deals with triangle s, circle s, oscillation s and waves ; it is absolutely crucial to much of geometry and physics . You'll often hear it described as if it was all about triangles, but I think that is missing much of the point. Waves and resonance are at the root of how matter works at the most fundamental level ; they are behind how sound and light move, and probably also how mind s and beauty work, on some level; so trigonometry turns out to be fundamental to pretty much everything. Any time you want to figure out anything to do with angle s, or turning, or swinging , there's trigonometry involved. The first thing to understand with trigonometry is why the mathematics of right-angled triangles should also be the mathematics of circles. Picture a line which can turn around one of its ends, like the hand of a

    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!

The program supports input of three sites and calculates the three arc distances, the area of the spherical triangle and the bearings between sites. Most spreadsheet programs should be able to import this file format. The graphic below illustrates the spreadsheet, before corrections on July 24, 2002. Previous downloads have "A to C" and "B to C" labels swapped for arcs and bearings. Let me know if there are other bugs in the applet.

    History of Ganit (Mathematics)
    Introduction
    Ganit (Mathematics) has been considered a very important subject since ancient times. We find very elaborate proof of this in Vedah (which were compiled around 6000 BC). The concept of division, addition et-cetera was used even that time. Concepts of zero and infinite were there. We also find roots of algebra in Vedah. When Indian Beez Ganit reached Arab, they called it Algebra. Algebra was name of the Arabic book that described Indian concepts. This knowledge reached to Europe from there. And thus ancient Indian Beez Ganit is currently referred to as Algebra.
