Modeling with Trigonometric Functions · Exercise 38
Construct an equation that models the described behavior.
A spring attached to the ceiling is pulled 7 cm down from equilibrium and released. The amplitude decreases by 11% each second. The spring oscillates 20 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.
