The sound of trigonometric equations by program The Geometer's Sketchpad (GSP) is a project of applied mathematics. The program is a mathematical program The Geometer's Sketchpad (GSP) to be applied to the course in mathematics lesson. Trigonometry and music In a musical score based on the combination. Trigonometric sine function of the corresponding equations that can cause noise. The first experimental design equation for the sound to suit the application. Starting from the equation Y = Asin (ωt + φ) physics experiment for the sounding by the equation Y = A sin (n * x * f), which requires that A is the amplitude f is. the frequency of the sound you are looking for, and n is the period of the graph sine and is looking to try to find an equation that used the program in the equation Y = a sin (2π * x * f)
would lead the equation. such testing frequency for sound-based music score based on the 8-by devices musical, including the tuner is used as a measure of volume to get the frequency sounding with musical notes background. The results of the experiment showed that in the first n that makes the sound of a symphonic musical score. Similar to the sound of the instrument and the program The Geometer's Sketchpad V.5 most n equals 2π part in the trials of the two measured using a tuner. The frequencies that are close to the most basic music notation. Find the right frequency with musical notes basic audio tracks (C) = 261.4, a radio (D) = 293.5, sound (E) = 330, a fast (F) = 349, a Salt (G) =. 196, Las audio (a) = 220 and 440, the noise (B) = 494 and high dosages (C◦) = 522.8 also has a music score that has been applied by presenting a melody on the program the.
