Fall 2022 MAT225 Lecture 202

(My AP Classroom from 1988-2019)
(Running Linux from 1994-2018)

Fall 2022 MAT225 Lecture 202:

Lecture 202, this week on Monday 10/03/2022, we spent the whole class practicing the Second Partials Test for Optimization! We applied the Hessian Determinant: 

D=(fxx)(fyy)-(fxy)(fyx)

to find out if we had a max, min or saddle point at a given critical point on the surface of z=f(x,y) such that fx=0 and fy=0 simultaneously. In fact, we found that most problems have fxy=fyx so the Hessian Matrix gives: 

D=(fxx)(fyy)-(fxy)^2

instead. Here's an example we did on Colab maximizing the volume of an Aquarium given a constraint.

This week we only had the one lecture as we are off on Wednesday for Yom Kippur. Next week we will continue our work on Partial Derivatives in Chapter 15 on Monday and have a homework clinic on Wednesday!

Review E Chain Rule & FILKs:

Last, but not least, remember this unit's mascot, Hedwig the Owl of Harry Potter fame, is here to cheer you on!

 

That's it for now. I hope you find this note is helpful and I hope that you will learn a lot this semester in my class!

 

Be well,

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, 

CSA: AP Computer Science A using CS50, this IDE and this IDE and OpenProcessing, 

CSI: Computing Science Independent Study using OpenMPI and 

CSL: Computing Science Lab which is a co-requisite for Calculus students using Computer Algebra Systems such as SAGE.
