This equation describes how a wave would be plotted on a graph, stating that y (the value of the vertical coordinate on the graph) is a function of the sine of the number x (the horizontal coordinate).... Now, you know that, at 1/4 of a period and 3/4 of a period, the displacement of a standing wave is 0 everywhere, so the problem is solved. But just to see that it is so, let's work it out in detail. Substituting t = 1/14 second into our standing wave equation gives for the amplitude 0.5 cos(7 p 1/14) = 0.5 cos( p /2).

The regular period for sine waves is 2Ï€, but the variable in this function is multiplied by Ï€; doing the division, the period of this particular function is going to be . Since I have to graph "at least two periods" of this function, I'll need my x -axis to be at least four units wide....30/04/2015Â Â· Wave period and wave frequency are reciprocals of one another. After watching this video you will be able to determine the period (and therefore the frequency) using a position vs. time graph of a

The frequency of a wave describes the number of complete cycles which are completed during a given period of time. As such, frequency is a rate quantity which describes the rate of oscillations or vibrations or cycles or waves on a per second basis. A common unit of frequency is the Hertz, abbreviated as Hz. A Hertz indicates the number of complete cyles per second. how to get big eyelashes naturally This equation describes how a wave would be plotted on a graph, stating that y (the value of the vertical coordinate on the graph) is a function of the sine of the number x (the horizontal coordinate)..

### 29/05/2012Â Â· Calculate the period and amplitude of a given function from its graph.

- The cotangent has a period of Ï€, and we don't bother with the amplitude. When you need to do the graphs, you may be tempted to try to compute a lot of plot points. But all you really need to know is where the graph is zero, where it's equal to 1, and / or where it has a vertical asymptote.
