Modeling with Trigonometric Functions · Exercise 40
Construct an equation that models the described behavior.
A spring attached to the ceiling is pulled 19 cm down from equilibrium and released. After 4 seconds, the amplitude has decreased to 14 cm. The spring oscillates 13 times each second. Find a function that models the distance, the end of the spring is from equilibrium in terms of seconds, since the spring was released.
