Lesson 1: Introduction To Trigonometry (Angles)


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
