Solving Second-Degree Trig Equations by Factoring • [4.4c] PRE-CALCULUS 12

Pre-Calculus lecture video demonstrating how to solve second-degree trig equations using isolation where factoring or the quadratic formula are required. Examples include both primary and reciprocal ratios, as well as both exact value (ie. π-fraction) and approximate (ie. decimal) solutions.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.

Corresponds to chapter 4, section 4.4 in McGraw-Hill's Pre-Calculus 12, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
