Intro to Reciprocal Trig Ratios • [4.3b] PRE-CALCULUS 12
Показать описание
The three reciprocal trig ratios, secant, cosecant, and cotangent (sec, csc, and cot) are introduced. Two examples are included:
1) Writing all six ratios (primary & reciprocal) given a right triangle
2) Using a calculator to evaluate reciprocal trig ratios
My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.
Corresponds to chapter 4, section 4.3 in McGraw-Hill's Pre-Calculus 12, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
