Precalculus notes

FACTORING starts Monday, and I am so excited! Algebra Anchor Chart for Math

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 corresponding…

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…

“I took some notes from the #LockdownMath series by @3blue1brown. They were taken from my perspective with some reorganizations and modifications, but hopefully they can help you recall or catch up with the lectures. Episode 1 introduces a simpler quadratic formula. (1/n)”
