Visual Analysis 4:23 Examples at 21:40 29:47 42:16 Even though this is corrected, I still forgot the power of 2 on the cosine in the denominator at minute 46:41

I have a full set of notes for Concavity: Testing for Concavity, Look at some graphical examples of where concavity may change and where you may find Relative Maximums and Minimums, Graphically compare a function with it's First and Second Derivative, Define Point of Inflection, and finally the Second Derivative Test. I then work through 3 examples of increasing difficulty.
