Question: Two waves in one string are described by the wave functions y1 = 3.0 cos (4.0x - 1.6t) And y2 = 4.0 sin (5.0x -

Two waves in one string are described by the wave functions
y1 = 3.0 cos (4.0x - 1.6t)
And
y2 = 4.0 sin (5.0x - 2.0t)
Where y and x are in centimeters and t is in seconds. Find the superposition of the wave’s y1 + y2 at the points
(a) x = 1.00, t = 1.00,
(b) x = 1.00, t = 0.500, and
(c) x = 0.500, t = 0.
(Remember that the arguments of the trigonometric functions are in radians.)
