Solving Word Problems Involving Trigonometric Equations (7.4.5)

Question 1

• One application of the trig functions can be seen in harmonic motion, such as the movement of a spring. The length or location of the spring can be modeled using trig functions. As such, many word problems involving harmonic motion will require you to solve trigonometric equations.

Question 2

• Review: Since trig functions are periodic, they will often have many solutions. To find all the possible solutions to a trig equation, find the solutions for a single period and then add multiples of the period to those solutions.
