Question

**TRIGONOMETRY*** Find the exact value of each of the following.

Answer 1

Have you tried reading the instructions given? It seems pretty straightforward. Just explaining the first step of teh first question below:



Looking at the fig. \(17\pi/6 = (12\pi + 5\pi)/6 = 2\pi + 5\pi/6\)

Note that from the figure, the angle of \(17\pi/6\) is equivalent to the angle \(5\pi/6\). So if you can calculate \(\sin{5\pi/6}\), you get your answer. Similar steps for the other questions.
