Two sinusoidal waves combining in a medium are described by the wave functions
y1 = (3.0 cm) sin π (x + 0.60t)
And
y2 = (3.0 cm) sin (x ─ 0.60t)
Where x is in centimeters and t is in seconds. Determine the maximum transverse position of an element 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.
