Two waves in one string are described by the following wavefunctions, where y and x are in centimeters and t is inseconds.
y1 = 2.5 cos(4.5x - 1.8t)
y2 = 3.0 sin(4.5x - 1.5t)
Find the superposition of the waves y1 + y2 at the followingpoints. (Remember that the arguments of the trigonometric functionsare in radians.)
(a) x = 1.00, t = 1.00
(b) x = 1.00, t = 0.500
(c) x = 0.500, t = 0
