1-5 Speed of a sinusoidal traveling wave

A wave traveling along the x-axis is described by the equation

where x and y are expressed in meters and t is in seconds. Find

  1. the amplitude,

  2. the wavelength,

  3. the period,

  4. the speed of the wave,

  5. the direction of motion of the wave, and

  6. the phase constant.
