Why Shadowfax? Our cluster is so fast that we named it after the Lord Of The Rings character!

Fall 2022 MAT225 Lectures 203 & 204
(My AP Classroom from 1988-2019) (Running Linux from 1994-2018)
Fall 2022 MAT225 Lectures 203 & 204:
Lecture 203, this week on Monday 10/10/2022, was about the Multivariate Chain Rule and the Gradient.
Lecture 204, this week on Wednesday 10/13/2022, was about Constrained Optimization using Lagrange Multipliers.
We also went over some homework problems from Chapter 15: Partial Derivatives.
It goes without saying that we coded in Jupyter Notebooks using Markdown, Latex, Python and Sympy to check our work!
Next week we will review preTEST2A on Monday 10/17/2022 and finish Unit02 on Wednesday 10/19/2022 with TEST2B. So, my next blog post won't be until we finish Lectures 301 & 302 in UNIT03 Chapter 16: Iterated Integration 3/28/2022.
Please remember the following pointers for TEST2B (just like TEST1B):
0) During any zoom session, remember: No pajamas, no bedrooms!
1) Place your webcam such that I can see your workspace during the exam. No cellphones! But Calculators, Laptops or Tablets are ok.
2) A copy of TEST2B is available on BlackBoard for download at 5:30PM so you can setup how you want to take the exam before class starts at 5:45PM (tablet and stylus or pencil and paper).
3) You may use anything on our BlackBoard site to help you during the test.
4) Consult our TEST2A solutions during TEST2B as a model of how to write complete answers.
5) Avail yourself of any computing environment you are familiar with to check your work: Graphing Calculator, Jupyter, etc.
6) Show all work supporting each answer in the spaces provided for each question or clearly labeled on separate sheets of paper.
8) You may leave class when you are done. Don't be in a hurry, you have all class period. Carefully check all your work, if possible, before you leave class.
9) Return clearly legible copies of all your work as a single pdf file via school email no later than 15 minutes after you leave class or 8PM, whichever comes first (gives you time to use CAMScanner or Squid to prepare your work for uploading). Class ends 7:45PM.
2) Karaoke entire song changing up the words (about STEAM).
3) You are Singing, Dancing or Playing an instrument.
4) You upload your video to YouTube and provide the url.
5) YouTube Description includes the lyrics.
XTRA CREDIT ARTICLES RUBRIC
(up to 5 articles = 1 bonus point each):
1) Cover Sheet is a Summary of the article.
2) FullPage, 12 pt, DoubleSpaced, 1" Margin.
3) Article has to be STEAM related
4) Article has to be a current event.
5) Copy of entire article is attached.
NOTE TO READER:
In recent years our independent study class has been about the care and feeding of Linux Clusters: How to Build A Cluster, How To Program A Cluster and What Can We Do With A Cluster?
BTW, Shadowfax is the name of the cluster we build! FYI, we offer 4 computing courses:
CSH: Computer Science Honors with an introduction to coding in Python using SAGE, IDLE, VIDLE and Trinket,
