Abstract

Trigonometric functions are occasionally incorporated into otherwise algebraic equations in order to increase the complexity of the question. While this is a clever way of assessing algebraic as well as trigonometric knowledge within the same question, it is not without its complications. This article illustrates how limitations in the maximum and minimum values of the sine and cosine functions might impact on such questions. Two examples are presented and explored, and possibilities for extension activities are suggested.
