Answer:
Step-by-step explanation:
The x value represents the time and y value represents the distance
Yes. the two events, e.g. LIKED and DISLIKED cannot both be TRUE at the same time
The maximum value is actually the maximum of y
So, you don't need to care about the stuff inside cosine function,
Cosine function is always within the range of [-1,1]
So here, ymax = -1 + 6* 1 = 5
