### Trig

 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 anglesPart 1: http://www.youtube.com/watch?v=U-bRh61OUQw 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-zKH5sKQProving (or Verifying) Trigonometric IdentitiesDeriving 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.Computing 1: http://youtu.be/B2A-mjkw_n8Computing 2: http://youtu.be/ybAob-dGHQEComputing 3: http://youtu.be/KjLsQDBEDM4Computing 4: http://youtu.be/SE7J6pNfWZ0Computing 5: http://youtu.be/9OM7INfptSo Special VideosPdf and Video Solutions to a Review for a test using the Lial book at MiraCosta Below are some Trig Videos by others who have posted on youtube.http://www.youtube.com/brmarzock22http://www.brightstorm.com/math/trigonometryhttp://www.youtube.com/user/patrickJMT#g/c/86281C72D802CE05Video showing how to use Trig to find a shadow from the sun blocked by a building: http://www.youtube.com/watch?v=MgNYskqNs3Y
