A wave on a string is described by the equation y=0.150 m sin (1.795x + 2010.6t) , where y is the vertical distance in meters, x the horizontal distance in meters, and t the time is seconds.
(i) What is the frequency of this wave?
(ii) What is the wave speed?
(iii) In what direction (positive or negative x direction) does the wave travel?
(iv) What are the first two times when the vertical position is y = 0.050 m?
