Class from 12/19

Chapter 4.4. We will begin to sketch graphs of rational functions. We will focus on end behavior, vertical asymptotes, and horizontal asymptotes.

Class on Block 12/16 and 12/17

Chapter 4.3. We will begin graphing polynomial functions today.

Class from 12/13

Chapter 4.2 Story Problems. We will be applying synthetic division and finding zeros of polynomials to real world context.

Class on Block 12/9 and 12/10

We will cover more of 4.2. We will use Descartes Rule, Upper and Lower Bounds, and Possible Zero Theorems to help solve for the zeros in a 4th or 5th degree polynomial.

Class on 12/6

This is the first day of 4.2. We will factor polynomial functions with real and complex zeros. We will also talk about the multiplicity of zeros.

Class on 12/4

PreCalc 4.1. We cover synthetic division and long division of polynomials.

Chapter 3 Review

We will review chapter 3 today. Tomorrow will test on the computational stuff and the stories problems and operations on functions stuff will be Friday. Good Luck!

Class from 11/15

Chapter 3.5. We will be performing operations on functions and identifying the resulting domains.

Class from Block 11/13-11/14

We will find the average rates of change for given intervals on curves using secant lines.

Class from 11/8

Chapter 3.3 continued. We will look at maximizing profit for a company. This includes finding y-intercepts, x-intercepts, and the vertex for a quadratic function.

Class from 11/7

We will look at graphing  quadratic functions using the completing the square method (vertical and horizontal shifts) and the quadratic formula (vertex). This is the start of chapter 3.3.

Class on 11/6

We will look at solving quadratic functions in the context of projectiles, business, and finding dimensions of rectangles. This is the end of chapter 3.2

Class on 11/4 and 11/5 Block Day

We will look at chapter 3.2 and solve quadratic functions using multiple methods.

Class on 11/1

We will discuss imaginary numbers today from chapter 3.1

Unit Circle

Below is a picture of the unit circle we were building in class. Remember that all of the points on the unit circle can be found using the 2 special triangles shown (30/60/90 or 45/45/90). Then you just need to reflect/rotate those triangles to find all 16 points. The second image is a completed unit circle with all coordinate points and angles.
