Trig

Click here for videos corresponding to the book I use in class. 

Click the link above for most of my Trig videos.

See the link above for Trig Videos in order of chapters of a book I use to teach Trigonometry.  See that link as that is where all my Trig videos are. I haven't organized by topic yet except on that page.



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.

I haven't made many Trig videos yet, but below are some Good Trig Videos by others who have posted on youtube.
