Math 2130 Section 101 Homepage

News & Announcements

08/04 Final grades have been sent out. 

      If you ever have any questions about this class, other math classes, or whatever, my door 
      is open. Stop by anytime (even just to say "Hi") - it would be nice to meet in person some day! 

      I hope you all have a great summer (what's left of it anyway)!

07/29 The Final Exam is Tuesday, August 4th at 8am (during our regular class period).

      There are several old final exams (with answer keys) posted. They're your best study tool.
      Beware that the finals from 2011 or earlier include irrelevant review problems. You are
      just responsible for Chapter 16 and our supplemental problems: Vector Calculus [Source: (.tex)]
      [You may skip 16.1 which was covered on Test #1. The parts of Chapter 16 covered on
       Test #3 are worth reviewing in preparation for the final.]

      Unlike the previous tests, I won't provide formulas on the final exam. But I will allow a page of
      notes. Please, prepare a page of notes for the final exam. On your page include any formulas 
      and worked out examples you might need. Preparing your page will likely help you prepare for the exam.
      Anything you want is fair game for this page: theorem statements, trig formulas, coordinate transforms,
      Jacobians, examples, motivational poetry, doodles, etc. I suggest at the very least to include spherical
      coordinate formulas and statements of the Big Theorems.

      Grades: If you score higher on your final exam than your lowest test, I will replace that test score 
              with the final exam score. So if your tests were 75, 85, and 77 but you make an 80 on the final,
              your scores become 80, 85, 77, (and 80 on the final). Thus the final presents a possibility of
              helping more than hurting!

      Announcements for the upcoming week (7/28-8/04)... 

      Lowest homework dropped.
      Final Exam score can replace lowest test score. (if it helps)
      Prepare a page of notes for the final.

      Notes on Grades: During a regular semester I usually drop a lowest quiz. 
                 However, I don't usually do this during the summer since we don't 
                 have many quizzes. Instead I tend to curve a little. On the other hand, 
                 I will drop your lowest homework. This means that if you already 
                 have scores you're happy with on the first three Maple homeworks, you 
                 may skip the last one (and I will drop that zero).

                 I will replace your lowest test with the final exam score (if it helps). 
                 So if your lowest test score was a 50 and you score 80 on the final exam, 
                 the 50 will be replaced by 80 in final grade calculations.

      Maple Homework #3 was due Yesterday (Monday)!

      Maple Homework #4 is due next Monday.
      Please turn in your homework via email no later than 6pm.

      Monday (YESTERDAY) Homework #3 WAS DUE!!!
          If you didn't get a "Got it!" email assume I didn't get it and resend it ASAP!!!!!
          Watch up to "Conservative VFs,..., and FTLI"
	  We met at 8 and 9am to answer questions and review for the test.
	 
      Tuesday (TODAY): Test #3.
                       (Hopefully I will have it graded tomorrow.)

      Wednesday: Watch up to "Green's Theorem"
                 We meet at 9am for questions.

              Also, Homework #4 is due by 6pm.
              If I don't receive Homework #4 by the end of the day, I will assume you are not turning it in and
              are just planning on dropping that zero.
				
      Tuesday (August 4th): FINAL EXAM -- Log in at 8am and I will send out your final (via email).

07/22 Test #3 is Tuesday (July 28th). It covers Chapter 15 & Section 16.2 as well as the handouts on 
      Double Riemann sums and vector fields. 

      Relevant handouts:
      Double Riemann Sums Supplemental Homework (.pdf) [Source: (.tex)]
      Vector Fields [Source: (.tex)]

      Examples:
      Spherical Cap Example (.pdf) [Maple: (.mw)]
      Examples of centroids handout [Source: (.zip)]
      Triple Integral Example (.pdf) [Maple: (.mw)]
      Triple Integral Example (.pdf) [Maple: (.mw)]

      I will provide the change of coordinate formulas for rectangular to spherical coordinates:
      
          $x=\rho\cos(\theta)\sin(\varphi), y=\rho\sin(\theta)\sin(\varphi), z= \rho\cos(\varphi)$.

      as well as the spherical coordinates Jacobian: 
      
          $J = \rho^2\sin(\varphi)$.

      If I give a center of mass or centroid problem, I will provide formulas for mass and moments.

      If I give a flux problem (see section 16.2), I will provide a formula for a flux line integral:
      
          $\int_C {\bf F}\,{\bf\cdot}\,{\bf n}\,ds = \int_C -N\,dx+M\,dy \quad$ where $\quad {\bf F} = \langle M,N \rangle$.

      The few problems that relate to Section 16.2 and probability density functions are noted below (see Fall 2009). 
      Beware: None of the problems involve computing means for prob. dens. functions.

      The material in our new textbook lines up pretty well with our old text, so old
      tests should be of value when studying. For the most part, Test #2's are relevant.

      Please turn in your (completed) Maple file and send it via email by the
      end of the day Monday. 5ish would be great.
 
      In case I didn't emphasize it enough: You should know about the Math Lab (free tutoring
      center). This summer's math lab meets via Zoom. Its hours of operation are Monday through 
      Thursday from 5 to 8pm. The lab's Zoom link is: https://appstate.zoom.us/my/genmatlearninglab.

      Wednesday: Watch videos up through "Center of Mass / Centroid: Curves" 
                 (this is the end of material covered on Test #1).
                 I will log in at 9am to answer questions.

      Thursday: Watch next two videos (up to "(Multivariable) Limits and Continuity").
                I will log in at 8am (and again at 9am) to answer questions 
                review for the test.

      Friday: Test #1 -- Log in at 8am and I will send out your test (via email).
              (See Test details below.)

      Monday: Watch up through "(Multivariable) Differentiability"
              Maple Homework #1 is due.

      Test #1 is Friday at 8am:
      -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
      The test will cover the parts of sections 11.1, 11.2, 12.1-12.5, 13.1-13.5, & 16.1.
      Our handout is worth studying: Differential Geometry Summary (.pdf) [Source: (.tex)]

      Old tests can be found here.
    
      While old tests are a good resource for getting an idea of what kinds of things I like
      to ask. Keep in mind that we switched textbooks last year so there are a few topics that aren't
      as relevant and a few that are missing. For example, you won't find much referencing torsion. 
      Also, keep in mind that summer school tests are longer because fall/spring tests are designed
      for 50min classes.

      Studying old tests is helpful, but make sure you also look over your notes from class
      and try lots of suggested homework problems.

06/30 We meet tomorrow at 8am via Zoom to discuss the syllabus and logistics.
      [You will need a password for the Zoom meeting - I will email it to you.]
      Feel free to check out the first few videos: Math 2130 Videos.

      We will have several Maple assignments throughout the term. Several videos
      reference demos that can be found on my Maple Examples page.

      I will provide a link & activation code so you can download Maple for free.
      Alternatively, you can access Maple and other software by logging on to a campus
      lab computer using udesk.appstate.edu

      You should be aware of the Math Lab – free tutoring for Math 2130 (and other math classes).
