1. Tower of Americas is a famous landmark in San Antonio, Texas. Greg is curiously watching the top of the
tower spin very slowly and is standing 630ft away from the tower. Let h be the height of the top of the
tower where it is rotating and be the angle of elevation to the tower from Greg.
a) Use h to write a function of
b) If Greg looks up to the tower from an angle of 50°, what would the height of the tower be?
2. There is a skateboard ramp that depict a sinusoidal function. The maximum and minimum points are in an
interval of about 25 ft horizontally and 6 ft vertically. The minimum point is 3 ft above the ground of the ramp.
Create a sinusoidal function that models the distance in d, at a given horizontal distance h.
