Circular Functions!

What is Circular Function? A Circular function can be defined in terms of an arc length and the coordinates of the terminal point of the arc on the unit circle. In this topic, we'll focus on studying its 3 basic Circular Functions which are Sine (Sin), Cosine (Cos), and Tangent (Tan) functions, and their Reciprocal Functions which are Cosecant (Csc), Secant (Sec), and Cotangent (Cot) functions. This is the image of the Unit Circle with angles in degree, radian measure, and their…

Precalculus will be moving beyond their introduction to functions and function notation from Algebra II and into a in-depth development of transformations. We will be applying transformations (translations, reflections, dilations, etc.) to many of the parent functions included in the image above (we will save trigonometry for the Spring!). Understanding transformations is a crucial link between the algebraic form of a function and its graphical behavior. We will spend a considerable amount…

Trig Hexaflexagon

My honors precalculus students saw the slope hexaflexagons my geometry students were using and asked when they would get something like that. I promised when we reached our trig unit, I'd whip something up. Below is the result as well as a video explaining how to assemble a hexaflexagon. My hope is that my students
