Ambiguous Case of the Sine Law • [2.3c] Pre-Calculus 11 

Sometimes you can have two possible solutions when using the sine law to find an angle! This video introduces and explains the ambiguous case of the Sine Law (two triangles possible) as well as the other cases that are possible (one or no triangles possible) when given an angle and two side lengths (and the angle is not between the two sides).
My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.
Corresponds to chapter 2, section 2.3 in McGraw-Hill's Pre-Calculus 11, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
