Trigonometry by sections I cover in my Trig class using the book Trigonometry by Dugopolsky, 3rd edition. To learn Trig, watch all these videos in order.

CHAPTER 1 - ANGLES AND THE TRIG FUNCTIONS

Section 1.1 - Angles and Degree Measure, including coterminal angles, degree, minutes, seconds, and arithmetic with degrees

Section 1.2 - Radian Measure, Arc Length, and Area of a Sector

Section 1.4 - The Trig Functions using the definition of an angle in standard position using ratios of  x, y, and r.

Section 1.5 - Right Triangle Trigonometry - defining Trig functions for acute angles in a right triangle using ratios of the sides of a right triangle

Section 1.6: The Fundamental Identity and Reference Angles

CHAPTER 2: GRAPHS OF THE TRIGONOMETRIC FUNCTIONS

Chapter 2 HW for Spring 2014 Trig Math 130 Class
