The Sound of a Sine Wave by Malin Christersson
Loading the math board and drawing, please wait…
This example demonstrates the mathematical representation and sound wave of a sine function. Core math concepts include sine function, coordinate geometry, vectors, and statistics. It uses GeoGebra commands/objects like f_1, f_2, g, f, A, h, button1, button2, text1, text2, text3. Suitable for high school and above students to learn function graphs, sound waves, and mathematical modeling.
GeoGebra Commands & Parameters
Numeric f_1(1.0)Numeric f_2(1.68)g(x) = (0.5 * sin(((((f_2 * 440) * 2) * π) * x)))f(x) = (0.5 * sin(((((f_1 * 440) * 2) * π) * x)))Numeric A(0.77)h(x) = (A * (f(x) + g(x)))
AI Drawing Prompt Reference
Draw a sine wave function graph, including two sine waves with different frequencies, one with a frequency of 440Hz (f(x)) and another with 1.68 times the frequency of 440Hz (g(x)). Add these two waves to create a new waveform h(x) with an amplitude of 0.77. First, draw f(x) and g(x), then calculate and display h(x).
