I have been intrigued and amazed by computer algebra systems since I first did simple algebra problems on an Apple II (I don’t remember the name of the program, though). The set of systems that we have available is quite amazing, yet, I think that we are missing some important tools.
This weekend was the Tulsa Homeschool Expo – thanks to everyone who came out to see us! We had a great time, and got to share with homeschooling parents our vision for how they can better raise the next generation of adults.
We are proud to announce that our recent title, Fossil Forensics: Separating Fact from Fantasy in Paleontology is currently Amazon’s #1 New Release in Paleontology! Have you ever wondered what is real and what is hype regarding the various fossil finds described in the media? This book has your answers.
You can currently purchase the book from Amazon or Barnes and Noble.

Dear students – thank you all so much for a great year! We explored quite a bit of new ground together, and I am proud of each one of you. I have not yet graded your finals / final projects yet, but I did peek at them, and I am fairly certain that every one of you that made it to the end finished well.
I am out of town this weekend, so will not likely finish your final progress reports until next weekend, but you should know now that I only have good things to say about all of you. All of you stepped it up this last semester and did very well.
This is your last week to finish your cart programs! We saw several great ones in class this week. Email me if you have any questions. Please bring your PRINTED programs to class. You should have the code printed as well as a printout of your page in action.
This week we did a transistor amplifier. Next week is the finals. It will be very similar to your last quiz, plus a few things from the previous semester.
This week we reviewed Taylor series as well as finding rotation volumes. Next week is the final – good luck!
In JQuery, they use a function named $ as a “magic function” which determines what it should do based on its parameters. If the first parameter is a CSS selector, it grabs all HTML elements that match that selector. If the first parameter is an HTML string, it creates HTML elements and text content to create the string. You can then do all sorts of things with the resulting values.
Information about the JQuery framework is available on the website jquery.com.
No homework this week – just focus on getting your cart done! It is due in class on May 17, but it wouldn’t hurt you to turn it in next week! Here’s what I would like:
- A printout of the code
- A printout of the cart in action (i.e., with stuff in your cart)
- A short printed paragraph describing the cart’s operation
If you aim for being done by this Wednesday, you can ask better questions in person.
This week we started looking at BJT transistors as current amplifiers, and built a circuit where a transistor controls a motor. We even visualized the inductive kick of the motor with an LED. I will have a new chapter for you this weekend on voltage amplification, and I *think* we will do an audio amplifier next week. The last week we will have a short exam, and may do a small project in-class.
This weekend I will try to have the chapter on Taylor series done. Next week we will go over Taylor series and maybe catch up on a few loose ends.
We are getting towards the end – keep up the good work!
Also check out their tutorial on Adding a Marker to a map.
The Google API key we used for class is
and if you missed class or used one of our computers, you can retype the code we finished with by looking at the images below:
- Add another marker to the map. Additionally, you should try to put the data in an array, and read the data in a loop.
- Keep working on your carts! I have seen many of you making good headway. Bring your current versions to class and we will keep working on them, or send me an email!
UPDATE – the new chapter has been added. The chapter is chapter 26, “Amplifying Power with Transistors”. Note that older chapters have been renumbered because I added an intro chapter on units.
This week we covered a little bit more about frequency response for capacitors and inductors, the basics of reactance and impedance, and what a resonant frequency is. We also started talking about transistors. My goal is to have the transistor chapter done for you by Saturday. There is a transistor chapter in the book right now, but it is incomplete and probably not very readable. I will update here when the new version is in. Homework will be for the transistor chapter.
UPDATE – the new chapter is ready. Download it and it is chapter 29.
There was no calculus this week. I will try to get your chapter done shortly.
Sorry I did not get this out in a timely manner. However, there is not much to talk about.
Be working on your shopping cart this week. Almost out of class days!
This week do the next chapter – “Inductors and Capacitors in Circuits” and do the problems.
There is no class this week so I will post the assignment in the next class notes.
