Arc Length • [4.1d] PRE-CALCULUS 12

The relationship between the arc length, radius, and central angle of a circle is examined, beginning with a proportion and developing a formula.

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

Corresponds to chapter 4, section 4.1 in McGraw-Hill's Pre-Calculus 12, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
