I'm sorry to laugh, but I certainly cannot help you with this problem. My math skills stop at about 6th grade.
i dontget how the textbook got the answer, h = -30cos[(1.43)x]° + 40
the question is:

As the wheel rolls, the mark moves in a circular motion.assuming that the paintball mark starts at its lowest point, determine the qeuation of the sinusoidal function that describes the hieght of the mark in terms of the distance the wheel travels.
