Fall 2022 MAT225 Lecture 201

 

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

Fall 2022 MAT225 Lecture 201:

Lecture 201, last week on Wednesday 9/28/2022, was all about Partial Differentiation! We discovered how to calculate fx, fxx, fxy, fy, fyy and fyx given any multivariate function f(x,y). We also found that the mixed partials fxy=fyx. Last, but not least, we played around with the Second Partials Test for Optimization!

This week we only had the one lecture as we were off on Monday for Rosh Hashanah. Next week we will continue our work on Partial Derivatives in Chapter 15 on Monday and we're off on Wednesday for Yom Kippur!

Elementary Calculus:

Review D Quotient 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.
