Lecture 1 Play Video	Special Triangles Special triangles have many uses in many math courses. This video addresses their derivation and application.
Lecture 2 Play Video	Unit Circle How do I make a unit circle? This is a guide to the making and application of the unit circle.
Lecture 3 Play Video	Trig to a Point How do I find the trig functions given a point on the terminal side of an angle in standard position. This is a how to guide for that process.
Lecture 4 Play Video	Right Triangle: Finding 5 Trigonometric Functions How do to find the other 5 trigonometric functions when one evaluation is given. This is a how to guide to the right triangle approach.
Lecture 5 Play Video	Proving Trig Identities (Part I) Proving trigonometric identities; the first example in a series of many.
Lecture 6 Play Video	Proving Trig Identities (Part II) Proving trigonometric identities; the second example in a series of many.
Lecture 7 Play Video	Proving Trig Identities (Part III) Proving trigonometric identities; the third example in a series of many.
Lecture 8 Play Video	Proving Trig Identities (Part IV) Proving trigonometric identities; the fourth example in a series of many.
Lecture 9 Play Video	Find Theta Known Value Find values of the angle in the argument of a trigonometric expression using right triangle trigonometry and the unit circle.
Lecture 10 Play Video	Evaluate the Sin In trigonometry we have to evaluate functions exactly. This video addresses the process.
Lecture 11 Play Video	Similar Triangles Corresponding angles of similar triangles are congruent. This video gives a numeric and algebraic examples of solving similar triangles using the property of proportional sides.
Lecture 12 Play Video	Graphing Sin(x) and Cos(x) This is a very compact video with explanation of the general from for the sin and cos functions, followed by 4 examples of using phase shift, vertical shift, amplitude and period to graph the functions.
Lecture 13 Play Video	Even and Odd Functions The video addresses the symmetry of even and odd functions and how to test algebraically whether or not a function is even or odd.
