Two sinusoidal waves combining in a medium are described by the equations  `y_1 = (3.0 cm) sin pi (x+ 0.60t)`  and    `y_2 = (3.0 cm) sin pi (x-0.06 t)`  where, x is in centimetres and t is in seconds. Determine the maximum displacement of the medium at  (a)x=0.250 cm,  (b)x=0.500 cm and   (c) x=1.50 cm.  (d) Find the three smallest values of x corresponding to antinodes.
