MAT225 - Multivariable Calculus: The Great Theorems! (SSII 2020 - WEEK04)

MAT225 - Multivariable Calculus:
The Great Theorems!
(SSII 2020 - WEEK04)

(More videos at http://www.patreon.com/calcpage2020)

Week04 started with Line Integrals in the plane to calculate Work and Flux. We practiced Double and Triple Integrals as well as Surface Integrals and Flux Integrals in Space. 

We reviewed the Fundamental Theorem for Line Integrals then we discovered Green's Theorem for Work in the Plane, Stokes' Theorem for Work in Space and the Diveregence Theorem for Flux in Space. 

Actually, we saw both forms of Green's Theorem. The other regards Flux Integrals in the Plane aka Green's Theorem in Normal Form. 

We talked about the Divergence Theorem as an experimental result when Gauss was studying Electric Fields so this theorem is also called the Gauss-Green Theorem and leads to Gauss' Law. We finished with a discussion of Maxwell's Equations and how they relate to Gradient Fields as well as the Divergence and Curl of a Vector Field. 

We finished the course this week by not testing on Thursday. So, this is our last blog post for the class. 

Week05 is all review and testing! This was great fun for me, even over Zoom. I hope you learned a lot this summer. Have a great rest of the summer.

MAT225 - Multivariable Calculus: Iterated & Line Integrals! (SSII 2020 - WEEK03)

MAT225 - Multivariable Calculus:
Iterated & Line Integrals!
(SSII 2020 - WEEK03)


Week03 was all about Special Integrals: Double and Line. We used Double Integrals to find Area, Volume and Mass. We also studied Vector Fields and Line Integrals. Then we calculated the Work done by a Vector Field over a path. We even discovered the Fundamental Theorem for Line Integrals!


Review Sheet - preTEST3A


Next week is all about the Four BIG Theorems: Green, Divergence and Stokes. It's actually 4 theorems since there's two forms of Green's Theorem: Work and Flux!

MAT225 - Multivariable Calculus: Partial Derivatives! (SSII 2020 - WEEK02)

MAT225 - Multivariable Calculus:
Partial Derivatives!
(SSII 2020 - WEEK02)
Week02 was all about Partial Derivatives and Applications of Partial Derivatives. We practiced finding first and second partials including mixed partials. Then we used the 2nd Partials Test for Optimization and LaGrange Multipliers for Constrained Optimization to optimize functions of the form z=f(x,y) and w=f(x,y,z). We also revisited Lines, Planes and Quadric Surfaces using Traces and Contour Plots! We even derived Linear Regression rules and Snell's Law!


When you watch our screencasts for this week you may notice that the first 2 are done in a similar style as those from Week01 and our 3rd recording for this week was a bit different. The reason for this is that my Samsung Galaxy NotePro 12.2 fried it's BlueTooth chip right before our first class. So, I ordered a Samsung Chromebook Plus to replace it. I should have had my new device before the first class of Week01 but my Amazon shipment was stolen at the Post Office and had to be reordered a week later??? (EDIT: This happened 2018 when I recorded these screencasts.)

Anyway, my first 5 recordings this summer were based on my broken tablet without it's Bluetooth Keyboard. That meant that I had to mirror the PC Desktop to my tablet so I could write notes by hand on the tablet as needed but I could also use the PC Keyboard to type code such that my students could see me doing both in the screencast and on the PC Projector and HDTVs all over the lecture hall. To accomplish this I ran TeamViewer, Xournal and SageCell on Chrome from the PC.

Now everything is back to normal as the Chromebook has a very similar look and feel to my tablet but it also has a flip away (ala Lenovo Yoga) keyboard and trackpad attached! All I have to do is mirror my Chromebook to the PC Podium. I'm using Teamviewer, Squid and SageCall on Chrome from the Chromebook. Teamviewer is a little laggy, I may try SplashTop Personal next week. Teamviewer and SplashTop are free to use if both devices are on the same WiFi network. (EDIT: This all happened 2018 when I recorded these screencasts live.)

Next week is all about Iterated Integrals, Area, Volume, Mass, Center Of Mass (optional) and calculating Work done by a Force Field in the plane! Think of Double Integrals as Partial Derivatives in reverse?

MAT225 - Multivariable Calculus: Vectors & Matrices! (SSII 2020 - WEEK01)

MAT225 - Multivariable Calculus:
Vectors & Matrices!
(SSII 2020 - WEEK01)


Week01 went off without a hitch! I think we had a pretty smooth introductory week for our first week of the July session of MAT225 Multivariable Calculus. We had great fun using SAGE as our 3D Grapher and Computer Algebra System instead of a graphing calculator!

"Introductory?" I hear you ask? Well, yes, it was introductory as in the topics should have been mostly review: 2D Vectors, Dot Products, 3D Vectors, Cross Products, Matrices and some Elementary Calculus (see filks below). We also looked at some 3D Graphs and Traces.

Our first test went well. A few students had trouble but they can catch up if they go to the Math Center regularly. I also drop the lowest grade, so there's room to improve!

Next week is all about 3D Graphs and Contour Plots, Partial Derivatives, Optimization, LaGrange Multipliers and the Chain Rule.

MAT225 - Multivariable Calculus: Getting Organized! (SSII 2020 - WEEK00)

MAT225 - Multivariable Calculus:
Getting Organized!
(SSII 2020 - WEEK00)

What About Elementary Calculus?

Welcome to my Summer Session II (July) MAT225 Multivariable Calculus aka Calc III class at Nassau Community College! I'm devoting the month of June to getting organized to teach this class. This is a bear of a course to teach in 5 weeks, so we have to get ready!

To that end, I just wrote my syllabus and set up my Blackboard page and Zoom meetings for this course and sent a mass email to all my students about joining my Blackboard. I also rewrote all my Class Notes, preTESTs, TESTs and Solution Sets! I used Squid a lot to write my notes. I'm going to use Squid to grade my tests too! Students can use Squid to write their tests solutions directly on the pdf I send them or they can print the TEST and use CamScanner to make a pdf to email their solutions back to me. 

I'm using Blackboard Email, Kaltura Video, Quickly Attendance and Quickly Grade Center extensively this summer since we are stuck working remotely during the COVID19 Pandemic.

What about Elementary Calculus? Well, I find that students taking this course tend to be a little rusty on concepts from Calculus I & Calculus II especially if they took those courses a while ago. Since Calculus III extends many concepts from Elementary Calculus (MAT122+MAT123 or AP Calclus AB+BC) to higher dimensions, I suppose that a little review is in order. So, we will start most classes (not testing days) with a short review of an important topic from Elementary Calculus (Limits & The Difference Quotient, Product Rule and Quotient Rule, Chain Rule, etc).

We will meet for 3 hours per night, 4 nights per week for 5 weeks straight from Monday 6/29/2020 to Thursday 7/30/2020. The first 2 days of each week will be devoted to new material. The 3rd day will be devoted to review in Zoom Breakout Rooms! The fourth day will be reserved for review and testing.

What follows is a summary of the first few posts I sent to my students on Blackboard:



FYI #1) Please make sure to download, print and return the attached form before our first meeting on 6/29!

FYI #2) TI83/84 are fine for Elementary Calculus but we need more powerful tech: 3D Grapher and Computer Algebra System. I've used graphing calculators such as the TI89/92 line as well as the TI nSpire CX CAS but even these devices are limited. So, we will primarily be using SageCell in class.
(Ti84C)

FYI #3) Since we will be using SageCell in class, I encourage you to use one Laptop or Tablet to follow the lecture plus another device to use for SAGE calculations. 
(SAGE Banner)


FYI #4) You may use the graphing calculator of your choice for basic calculations (algebra, trigonometry, preCalculus, Elementary Calculus) but you will want to use SageCell for Multivariable Calculus. SageCell is based on FLOSS. I use FLOSS every day, do you? FLOSS stands for Free Linux Open Source Software. Paramount among these software packages is Python. We will be learning Math Pythonically! SageCell is free to use online so you can access it in class and at home. There's a commercial version of SAGE called CoCalc if you prefer, but it costs $5 per month per user. Both of these systems run in the cloud, aka Google Compute Platform (GCP).
(Sample SageCell)

FYI #5) I will record ScreenCasts in class using MP4 format whenever I cover a new topic using Screencast-o-matic on my Chromebook. I will also be sharig these files via Kaltura on Blackboard.
(Screencast-O-Matic)

FYI #6) Our room was supposed to be B218 which is a large lecture hall spanning 2 stories of the B Cluster. The A/C is pumped in from the roof of the building and is very strong. Cool air tends to pool in the lower level of the room, please dress warmly. This doesn't matter anymore since were working remotely from home!
(Kindle Fire HDX Tablet)

FYI #7) So, if I'm not using the MarkerBoards/WhiteBoards in B218, we'll need an IWB (Interactive WhiteBoard aka SmartBoard), right? Nope, we don't have a SmartBoard, so I was going to mirror (with TeamViewer or SplashTop app) my PC Desktop to my Samsung Galaxy NotePro 12.2 Android Tablet or Samsung Chromebook Plus and write on my Tablet as if it were a SmartBoard! Now I have a Zoom studio at home made up of 3 Chromebooks instead (one for my notes, another to broadcast the lesson to you and a third to monitor what you see on your end)
(My Desktop - B218 Front)

FYI #8) B218 also has a PC Media Center/Podium with multiple PC Projectors and HDTVs so you can see everything I do on my PC even if you sit in the balcony! I was going to be doing everything on my PC so you wouldn't miss a thing if you sit in the upper level or if you miss class (aka on the ScreenCast).
(Your View - B218 Rear)

I got you covered!
Hope that was helpful!
See You in July!

Well, that's all folks.
