Basic Sine & Cosine Graphs • [5.1a] PRE-CALCULUS 12

Want to really understand why the graphs of the basic sine and cosine functions look the way they do, and how they're connected to the unit circle?, This video introduces these two important basic functions from a graphically and numerically, along with related features and terminology (eg. amplitude, period, maximum/minimum values, domain & range).
My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.

Corresponds to chapter 5, section 5.1 in McGraw-Hill's Pre-Calculus 12, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
