I thought that was the first thing I did under useful equations. Are those two equations not right for the two waves traveling in opposite directions?

Homework Statement y' = (0.80 cm) sin[(π/3 cm-1)x] cos[(45π s-1)t] (a) What are the amplitude and speed of the two waves (identical except for direction of travel) whose superposition gives this oscillation? (b) What is the distance between nodes? (c) What is the speed of a particle of...
