http://www.greenemath.com/ In this course, we will begin our study of trigonometry. We will begin by reviewing some basic concepts of angles and angle relationships from geometry. We will then more into learning about the six trigonometric functions sine, cosine, secant, cosecant, tangent, and cotangent. From there, we will work on deriving some basic trigonometric identities known as the reciprocal identities and the Pythagorean identities. These identities will help us to find unknown trigonometric function values. 0:00:00 Review of Angles 0:12:09 Degrees, Minutes, and Seconds 0:24:53 Standard Position and Coterminal Angles 0:34:27 Angle Relationships, Transversals, Similar Triangles 0:52:23 The Six Trigonometric Functions 1:05:28 Finding Missing Trigonometric Function Values 1:24:37 Pythagorean Identities
