    Extractions: Similar figures P LANE TRIGONOMETRY IS BASED on the fact of similar figures. (Topic 1: Ratio and proportion .) We saw: Figures are similar if they are equiangular and if the sides that make the equal angles are proportional. Right triangles will be similar, however, simply if an acute angle of one triangle is equal to an acute angle of the other. ( Theorem 14 .) Thus in the right triangles ABC, DEF, if the acute angle at B is equal to the acute angle at E, then those triangles will be similar. The sides that make the equal angles will be proportional. If CA is half of AB, for example, then FD will also be half of DE. To be more specific, if angle every sides will be in the same ratio. A trigonometric Table is a table of ratios of sides. In the Table, each value of sin is the ratio of the opposite side to the hypotenuse in every right triangle having that angle. Thus we read in the Table Example. Indirect measurement.

64. Mathematics Problem Writing Service For School, Math Leagues
    Mathematics problems for middle school and high school math competitions with topics range from algebra and geometry to probability and trigonometry.  
    http://www.virtu-software.com/math/
    
    Extractions: One of the great ways to inspire students to learn more about mathematics is to hold competitions in which students compete against students from their own school, or from around the state, or country. Problem solving skills are sharpened, while teamwork is encouraged. The end result is that students think more critically, understand concepts better, and learn to work well together. Douglas Twitchell, who maintains Virtu Software's Problem Of the Week page, experienced this first hand throughout his elementary, secondary, and college career. Twitchell is a former competitor and award winner in a variety of state and national math competitions. He has won awards and recognition in leagues such as MAML, NEML, ASMA, NEAML, and in college he ranked in the top 150 in the prestigious William Lowell Putnam exam. Whether it's a regional, state, or school competition, consider hiring Doug to write problems for your math meet. The problems are carefully crafted and written, with diagrams where appropriate, all cleanly formatted for printing. Each problem is proofed to guarrantee both accuracy and clarity. Proofing is done by a high school math teacher and math team coach, and the proofing cost is included.

    Extractions: Trigonometry (from the Greek trigonon = three angles and metro = measure) is a branch of mathematics dealing with angles triangles and trigonometric functions such as sine cosine and tangent . It has some relationship to geometry , though there is disagreement on exactly what that relationship is; for some, trigonometry is just a subtopic of geometry. edit The origins of trigonometry trace to the cultures of the ancient Egyptians and Babylonians and Indus Valley civilizations, over 3000 years ago. Indian mathematicians were the pioneers of variable computations algebra for use in astronomical calculations along with trigonometry. Lagadha is the only known mathematician today to have used geometry and trigonometry for astronomy in his book Vedanga Jyotisha, much of whose works were destroyed by foreign invaders on India. Greek mathematician Hipparchus circa 150 BC compiled a trigonometric table for solving triangles. Another Greek mathematician, Ptolemy circa 100 AD further developed trigonometric calculations. The Silesian mathematician Bartholemaeus Pitiscus published an influential work on trigonometry in and introduced the word to the English and French languages.

    Extractions: 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.

    Extractions: Search Advanced Site Map A-Z Index Professional Development ... Printer-friendly version Grades Eight Though Twelve - Mathematics Content Standards. Trigonometry uses the techniques that students have previously learned from the study of algebra and geometry. The trigonometric functions studied are defined geometrically rather than in terms of algebraic equations. Facility with these functions as well as the ability to prove basic identities regarding them is especially important for students intending to study calculus, more advanced mathematics, physics and other sciences, and engineering in college. Students understand the notion of angle and how to measure it, in both degrees and radians. They can convert between degrees and radians. Students know the definition of sine and cosine as y- and x- coordinates of points on the unit circle and are familiar with the graphs of the sine and cosine functions. Students know the identity cos (x) + sin (x) = 1: 3.1 Students prove that this identity is equivalent to the Pythagorean theorem (i.e., students can prove this identity by using the Pythagorean theorem and, conversely, they can prove the Pythagorean theorem as a consequence of this identity).

    Extractions: SOUTH ASIAN HISTORY Pages from the history of the Indian sub-continent: Science and Mathematics in India History of Mathematics in India In all early civilizations, the first expression of mathematical understanding appears in the form of counting systems. Numbers in very early societies were typically represented by groups of lines, though later different numbers came to be assigned specific numeral names and symbols (as in India) or were designated by alphabetic letters (such as in Rome). Although today, we take our decimal system for granted, not all ancient civilizations based their numbers on a ten-base system. In ancient Babylon, a sexagesimal (base 60) system was in use. The Decimal System in Harappa In India a decimal system was already in place during the Harappan period, as indicated by an analysis of Harappan weights and measures. Weights corresponding to ratios of 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, 200, and 500 have been identified, as have scales with decimal divisions. A particularly notable characteristic of Harappan weights and measures is their remarkable accuracy. A bronze rod marked in units of 0.367 inches points to the degree of precision demanded in those times. Such scales were particularly important in ensuring proper implementation of town planning rules that required roads of fixed widths to run at right angles to each other, for drains to be constructed of precise measurements, and for homes to be constructed according to specified guidelines. The existence of a gradated system of accurately marked weights points to the development of trade and commerce in Harappan society.

    Extractions: 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.
