The movie at left shows how a standing wave may be created from two travelling waves. If two sinusoidal waves having the same frequency (and wavelength) and the same amplitude are travelling in opposite directions in the same medium then, using superposition, the net displacement of the medium is the sum of the two waves.
Although this equation involves sine and cosine waves, it follows the same conversion equations as do simple vectors. Figure 8-9 shows the analogous vector representation of how the two variables, A and B , can be viewed in a rectangular coordinate system, while M and θ are parameters in polar coordinates.
Calculator Use. This online trigonometry calculator will calculate the sine, cosine, tangent, cotangent, secant and cosecant of angle values entered in degrees or radians. The trigonometric functions are also known as the circular functions.
On The Mathematics of the Sine Wave y(x) = A*(2πft + ø) Why the understanding the sine wave is important for computer musicians. The sine wave is mathematically a very simple curve and a very simple graph, and thus is computationally easy to generate using any form of computing, from the era of punch cards to the current era of microprocessors.
