How do you graph and list the amplitude, period, phase shift for
Sep 15, 2016 · The next half, for one full wave, is from (pi/2, -3) to (pi, -3), with zenith ( crest ) at (3/4pi, 0). Now, you can make it for this Table: I lack facility for making it, for you. (x, y): (0, -3) (pi/4, -6) (pi/2, -3) (3/4pi, 0) (pi, -3) Either side outside, it is lateral (horizontal ) successive movement of this single wave, through the period ...
How do you graph y=4cos2(x-pi)+1? - Socratic
Nov 29, 2016 · The graph is a cosine wave about y = 1, with amplitude = 4, period = pi. The graph is inserted. y-1=4cosx(x-pi)=4cos(2x-2pi) =4cos(2pi-2x)=4cos2x. This represents a cosine wave about y - 1. The period is (2pi)/2=pi and the amplitude about y = 1 is 4. Graph is inserted. Here, pi=3.14, nearly. Look for graph for one period with in [-pi/2, pi/2]=[-1.57, 1.57] Correspondingly, …
How do you find the amplitude and period of a function
Amplitude = 1 and period = pi/2. The amplitude and period of y = a sin (bx + c ) are a and (2pi)/b. Here, a = 1 and b = 4. This sine wave oscillates between the crests at y = 1 and the lowest points at y = -1, periodically, with period pi/2 for one full wave.
How do you find the amplitude, phase shift and period of
Jul 15, 2015 · The amplitude is |-2|=2, the phase shift is 0, and the period is (2pi)/(4/3)=(3pi)/2\\approx 4.7124 Assume that B>0. For a function of the form y=Asin(Bx+C)+D=Asin(B(x+C/B))+D, the amplitude (half the vertical distance between the high point and low point) is |A|, the period (horizontal peak-to-peak distance) is (2pi)/B, the vertical …
The period of a wave is found to be 50 seconds. What is the
Sep 20, 2016 · The period of a wave is found to be 50 seconds. What is the frequency of the wave? Physics. 1 Answer
What causes the pitch to change of a siren to change as it
Apr 24, 2018 · The Doppler Effect causes a siren to change pitch as it goes by you. The Doppler Effect is the apparent change in the frequency of a wave due to the relative motion between the source and the observer. When a emergency vehicle speeds by you, the pitch of its siren first increases and then decreases. This is because as the source of sound moves towards you, …
What is the wave speed if the wavelength is .5 m and the ... - Socratic
Apr 27, 2018 · To calculate the speed of a wave, simply multiply its wavelength and its frequency (given that you are provided with the two variables). This makes sense, since the unit for speed (m/s) matches that of the product of wavelength (m) and frequency (Hz). Keep in mind that one Hz is equivalent to one inverse second (#s^-1# or #1/s#).
How do you calculate frequency of a wave? - Socratic
Jul 14, 2014 · Thanks for your question regarding the calculation of the frequency of a wave. In light (as in sound), the equation for determining frequency involves knowing the speed of the wave, the wavelength of the wave, and the wave's frequency. The equation is: Speed (or velocity) = wavelength X frequency If you are dealing with an electromagnetic wave and it is travelling …
How do you graph #y=sec (x/2)#? - Socratic
Feb 7, 2018 · Please read Explanation. The first step to graphing a reciprocal function is to expand the function with the definition of the reciprocal function. In this case: sectheta=1/costheta So, to put it in the actual function: sec(x/2)=1/cos(x/2) Now, graph the wave of cos(x/2) with a dotted line. The graph starts at (0,1) and has a period of (2pi)/(1/2) or 4pi. (drawn in green) …
