Click here for videos corresponding to the book I use in class, and for the various topics I have made videos on for Trig. You can find the topic you want as I stated what each section of the book covered, and what is on each video. I haven't organized by topic yet except on that page.

Below are a few by topic.

Special Angles--how to find trig functions of special angles

Video Solutions for Graphing Handout (see attachment below): 
Part 1:This video shows how to graph these 4 trig functions from a Graphing Handout: y=2sinx, y=(1/2)sinx, y= - sinx, y = -2sinx: http://youtu.be/fWp-zKH5sKQ

Deriving Trig Identities: Derives the formulas and has examples using the formulas for many common Trig identities such the sum and difference identities like sin(A+B), the double angle identities like sin(2A), and the half angle identities like sin(A/2)

Computing using Trig Identities: These are problems where you are given some info, and then need to compute something else. For example, you might need to compute sinA if you know the cos2A, etc.
