Interpreting trigonometric graphs in context


Hugo has a pin attached to one of the spokes of his bike's wheel, for decoration. The height of the pin above the ground, in centimeters, is modeled by H(t) where t is the time in seconds. The function is graphed below, along with one segment highlighted.
A trigonometric wave labeled H on a t y coordinate plane. The y-axis scales by five. The t axis scales by one. The wave starts at its minimum at (zero, ten). The range of the wave is from ten to fifty. There is a highlighted vertical arrow that extends from the midline at y equals thirty to the maximum at (one and one half, fifty).
