07/11/2016

Lesson on understanding the difference between radian and degree measure, and converting radian to degree and vice versa. These two are ways on expressing angles in trigonometry. A degree-measured angle has equivalent radian measures for that degree. Likewise, a radian-measured angle has equivalent degree measures for that radian.
7:55 30 degrees to radian
9:14 2pi/3 to degrees
