# Chapter2Solving Trigonometric Equations

Weather patterns often occur in a periodic fashion as the Earth revolves around the Sun. For example, the average daily temperature in a city typically looks like a trigonometric function. However, in this case the period of the function would be 365 days, not \(2 \pi\text{.}\) In order to model more complicate phenomena like average daily temperature we will need to make use of generalized trigonometric functions.
