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....
