Calculus Review – some helpful hints

Having trouble with the WeBWorK?  First, don’t panic – it’s a lot to remember!!  But do be prepared to put in some time re-learning stuff from Calculus I and II.  I’ve picked out a few video resources for you that hit some of the most important techniques  (I tried to find videos that were focussed on examples, rather than theory, since this is meant to be review).

Comments are welcome (just click the “leave a comment” button above).

  • Like a video? Leave comment and let me know.
  • Dislike a video (it wasn’t helpful/ it was confusing)? Let me know.
  • Need help with another topic (like the product rule, or equations of tangent lines, or something else)?  Let me know.
  • Have a video or other resource to suggest? Let me know!

Derivatives: The Chain Rule (similar to Problem 4):  This video is short and sweet, a single example using the chain rule with a logarithmic function.

 

Integrals: U-Substitution (similar to Problems 5 & 6):

This video has three examples – the first two are most similar to what you will see in WeBWorK (the last one is a little trickier – but could be useful in the future):

 

Integration by Parts (similar to Problems 7 & 8)

This video also has a few examples – the first two will be most useful for the WeBWorK:

Getting Started with WeBWorK

WeBWorK is accessible from on and off campus, anywhere you have access to the internet.  Your first two WeBWorK assignments are due next Tuesday, February 7th, at midnight.

To get started, you must complete the following three steps.

Step 1.  Log in to WeBWorK here:  http://mathww.citytech.cuny.edu/webwork2/MAT2680-S17-Reitz/.  I have created Usernames and Passwords for each student registered for my class.

Username.  Your username for WeBWorK consists of your first initial plus your last name, all lowercase (for example, John Smith would have username ‘jsmith’).

Password.  Your temporary password is the same as your username (if your username is ‘jsmith’, your password is currently ‘jsmith’).

Step 2.  Change your password and update your email address.  To do this, select “Password/Email” from the main menu on the left.  Use whatever email address you like (I suggest using one that you check often).

Step 3.  Complete the first two assignments, by clicking on them on the main screen.

If you have any trouble – either with logging in, or with completing the assignment, post a comment here or send me an email and I will get back to you.

WeBWorK Tips:

  1. Click on a problem to see the details (the list of problems appears in the menu on the left).  Enter an answer and hit “Submit Answers”.  Don’t worry, if you get it wrong you can try it again.
  2. You can work on the problems in any order you wish.  You can do some problems now, and come back and do the rest another day (your work will be saved, as long as you submit your answers).
  3. If you want to print out a copy of the assignment, click on the assignment name in the main menu on the left, and then click the link in the main screen area that reads “Download a hardcopy of this homework set.”

Welcome and Getting Started

This course is MAT 2680, Differential Equations, taking place in the Spring 2017 semester with Professor Reitz.  We will be using this website in a variety of ways this semester – as a central location for information about the course (assignments, review sheets, policies, and so on), a place to ask and answer questions, to post examples of our work, and to talk about  mathematics, physics, reality and so on.

Getting Started

Anyone on the internet can look around the site and see what we are doing, and even leave a comment on one of the pages.  However, only registered users can create new posts and participate in the discussion boards.

How do I register?

You will need to do two things:

  1. If you have not used the OpenLab before, you must first create an account.  You will need access to your citytech email address  for this.  Detailed instructions for signing up on the OpenLab can be found here.
  2. Once you have created an account on the OpenLab, log in and then join this particular course, 2017 Spring – MAT 2680 Differential Equations – Reitz.  To do this, first click the “Course Profile” link at the top left of this page (just above the picture).  Then click the “Join Now” button, which should appear just underneath the square picture of a peaceful natural scene.

Problems with the OpenLab or with your CityTech email:

Please let me know if you run into any problems registering or joining our course (send me an email, jreitz@citytech.cuny.edu).  I also wanted to give you two resources to help out in the process:
