Unformatted text preview: as we know at t=0 and x=0 we are at the maximum, implying phi=pi/2. Plugging in values for amplitude, period, wavelength, and equilibrium at t=0 and x=1 and comparing either a - or + sign, it can be seen that the - sign will yield the correct value. The minus sign in the equation corresponds to movement to the right. So, Bill's cow's must be sending the signal. Question 3 Answer: y(x,t) = 0.5 meters * sin [ (2 * pi * t / (4 seconds) - 2 * pi * x / (8 meters) + pi/2 ] + 1.6 meters. This equation is obtained by plugging in the information from above....
