Two waves in one string are described by the wave functions
y1 = 2.90 cos (3.80x - 1.50t)
y2 = 3.90 sin (4.80x - 2.10t)
a) where y and x are in centimeters and t is in seconds. Calculate the superposition of the waves y1 + y2 at the points x = 1.50, t = 1.40. (Remember that the arguments of the trigonometric functions are in radians.)

This question requires you to enter the given values into the equation, and add y1 and y2 together.
y1 = 2.90 cos (3.80(1.50) - 1.50(1.40))
y2 = 3.90 sin (4.80(1.50) - 2.10(1.40))
y1 + y2 = -6.12 cm
y1 = 2.90 cos (3.80(1.50) - 1.50(1.40))
y2 = 3.90 sin (4.80(1.50) - 2.10(1.40))
y1 + y2 = -6.12 cm
