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.

Science In India: History Of Mathematics: Indian Mathematicians And Astronomers, Describes Indian mathematicians such as Aryabhatta who modelled the solar system, Bhaskar, Varahamira, and others who made important contributions in the fields of trigonometry, algebra, and classical analysis. http://members.tripod.com/~INDIA_RESOURCE/mathematics.htm

var cm_role = "live" var cm_host = "tripod.lycos.com" var cm_taxid = "/memberembedded" Check out the NEW Hotbot Tell me when this page is updated 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.

Please note that getting 1/3 of an angle is equivalent to trisecting it, a classic impossible problem! ( Advanced - because the answer depends on solving a cubic. The answer is rather dirty-looking, anyway). back to top And there are as many more as you care to memorize (always a mistake!).

@import "/prod_css/shared/import.css"; HELP STORE SEARCH: Site Colleges Home College Board Tests CLEP: Exam Descriptions College Algebra-Trigonometry The College Algebra-Trigonometry examination covers material usually taught in a one-semester course that includes both algebra and trigonometry. Such a course is usually taken by students who have studied algebra and geometry in high school, but who need additional study of precalculus mathematics before enrolling in calculus and other advanced courses at the college level. Approximately half the test is made up of routine problems requiring basic algebraic and trigonometric skills; the remainder involves solving nonroutine problems in which candidates must demonstrate their understanding of concepts. The algebra part of the test includes questions on basic algebraic operations; linear, and quadratic equations; inequalities and graphs; algebraic, exponential, and logarithmic functions; and miscellaneous other topics. The trigonometry part of the test includes questions on trigonometric functions and their relationships, evaluations of trigonometric functions of positive and negative angles, trigonometric equations and inequalities, graphs of trigonometric functions, trigonometry of the triangle, and miscellaneous other topics. It is assumed that the candidate is familiar with currently taught algebraic and trigonometric vocabulary and notation with both radian and degree measure. The College Algebra-Trigonometry examination requires all of the knowledge and skills required by the separate examinations in College Algebra and Trigonometry. The combined examination contains 63 questions to be answered in 90 minutes. There are three separately timed sections. Part 1 consists of 30 algebra questions in 45 minutes; an online scientific calculator is provided although there are no questions that require a calculator. Part 2 contains 13 questions to be answered in 15 minutes and does not allow the use of a calculator. Part 3 contains 20 questions to be answered in 30 minutes and requires the use of an online scientific calculator.
