The trigonometric function by the sounds from the equation, The Geometer's Sketchpad (GSP) is a mathematics project by using mathematical programs, The Geometer's Sketchpad program (GSP). Introduced with the math in trigonometry lessons and music. In regard to the basic musical notes sound together by. The trigonometric sine function, study the equation corresponding to the equations that can cause sound. Design of experiments 1 find the equation to the sounds that are appropriate to the program starting equation Y = Asin (ω t + ϕ) physics experiment, find the equation for the cause by setting the equation Y = A sin (n * x * f), A is the amplitude of the frequency f is stereo music search and n is the peninsula of graph design and is the value you want to experiment to find the equations of the principal agent in the equation Y = A sin program (2 π * x * f) Such equations is by finding the value of frequency for sound-based music notation Basic 8 through musical devices include a tuner is used as the audio level meter to get a frequency that causes the sound matches the basic music notation. Results from experiments in part 1 found that a value of n that makes the sound of the musical sound are similar to the melodious musical and appropriate with The Geometer's Sketchpad program most V.5 n equals 2 π. 2. in the trial section, measured using the tuner to find frequencies that are near to the most basic music notation. It found that the frequency that suits the basic musical notation is (C) = (D), 261.4 = 293.5, with sound (E) = (F) Fahrenheit, 330 = 349, Sol (G) = 196, La (A) = 220 and 440, (B) = voice and speech and high dosages of 494 (C◦) = 522.8. It has also brought a musical that has been applied by the presentation of a melody. The Geometer's Sketchpad on the program (GSP).
