We will define the unit circle and define the radian as a measure of an angle. We will then graph the trig functions using radians because radians are real numbers. We will do an application problem.

Lesson Comments
We defined the term radian and then compared radian measure to degree measure. We created a graph to show the hours of daylight for one year in Boston, MA.
We will study graphs related to the trigonometric functions beginning with the sine function. The graph is periodic and can be used to model periodic natural events such as the time of sunrise.
