Welcome to the webpage for Pre-Calculus. Here you will find additional resources that we may use in class.
Week 7 – LAST WEEK :D
Hi all: This is the last week of assignments. All work MUST be turned in by June 10th. For a couple of you who have not done the work... might want to get on that.

Post Spring Break Update
By now, all of you should have gotten an e-mail from Mrs. Demaio about the upcoming plan. We have a staff meeting on Wednesday to finalize things. Then we will start assigning things for you to do next week. Monday is math day, so expect math updates here. I have created a Discord Channel, if you wish to use (not mandatory), where you can post questions, ask classmates for help, ask me for help. It has voice channels so we could talk if you're having trouble, and even screen sharing so I could show you how to do things. https://discord.gg/GkePaGZ is the invite to the channel. I can also do Google Meet, but that has more limited capabilities.

Week 1 Update - Pre-Calculus
Hello, Pre-Calculus
I know that what is happening right now is unprecedented, and we are all unsure about what the next steps are and what will be happening. I hope you are all staying safe and healthy in these times. We are going to be unable to complete everything that we set out to complete in Pre-Calc this year. Thus, there may need to be some self-learning for extension in order to best keep your math skill sharp. In light of that, I am going to be posting some things for you to look at during your time while we are out of the classroom for you to look over. As with other classes, this is for extension learning (not for a grade), but it is still things that were important enough to be included in our regular instruction.

Things to look at/do.
1. You can always continue on your paths in ExactPath, this will help keep your math skills up to date. Khan Academy (when linked to your College Board and PSAT results) can also be a great resource for you
2. Work on any assignments that you may have missing for class
At far as work on topics specific to Pre-Calculus
1. Continue to look at and review any material from Sections 4.5-4.8 - We will review it when we come back to school but we were almost done, so you should be able to do most everything from those sections.
2. Look forward to sections 6.1-6.4 (skip Chapter 5), as Chapter 6 deals with extensions of applications of Trigonometric Functions.
