WebAssign login is handled through Canvas. To access WebAssign:

• Login to Canvas and select this specific class:
     Math 20C - Calculus&Analyt Geom/Sci&Engnr - Fulek [FA20]
• Go to the "Modules" page and select "WebAssign".

The first time you "Access WebAssign", you will need to create a "Cengage account" or login to your Cengage account if you already have one. Canvas will remember your Cengage account info, so you won't normally have to re-enter it. If you take another class using WebAssign, you should link it to the same Cengage account. (Cengage is the company that owns WebAssign.) On subsequent logins, you can either login to Canvas and select "Access WebAssign", or you can login with your Cengage account at webassign.net.

WebAssign access code and grace period:

• See the Syllabus for options to get an access code for WebAssign, whether with the book or separately.
• WebAssign has a grace period with free access for the first two weeks of class. After that, you either need to enter your access code (if you bought the book bundled with a code) or purchase access within WebAssign (after first logging in through Canvas as described above). If you are waitlisted or still working out your schedule and not sure if you'll stay in the class, then hold off on entering the code until required.
• If you already have a multi-term access code to this textbook (because you took Math 20C before, for example) then you may use the same code. If possible, you should use the same account for each class. If you were using a different account, then contact WebAssign's Customer Support to transfer the code.

Problems logging in:

• If you used WebAssign before, it may not be the same WebAssign account. You must login to WebAssign for this class via WebAssign as described above.
• WebAssign has different ways to set up class accounts. We're doing it through Canvas. We are not using a "Course Key" with self-enrollment. If you get to a screen requiring a "Course Key" when trying to login, then something went wrong--try logging in again through Canvas.
• Canvas's roster and WebAssign's roster are synched roughly once a day, so if you've recently added to the course, you may need to wait a day or two to log in.
• Most login issues can be resolved with the following generic steps: restart your browser; restart your computer; try a different browser; try a different computer.
• If these solutions don't work, WebAssign's technical support will be happy to help.

• If you believe that WebAssign is grading a problem incorrectly or that there is an error in a question, make a post about it on Piazza. The overwhelming majority of the time, such issues are caused by minor input formatting errors rather than actual bugs with WebAssign.
• WebAssign does not have detailed solutions for this textbook. Check the student solutions manual to see if a similar problem has a worked-out solution. "MarsVectorCalc6 1.1.009" indicates the problem is adapted from our textbook, Chapter 1.1, problem 9, but may have changes such as different numbers.
• Avoid the "Submit Assignment" button at the bottom; it is not needed if you submit each problem as you do it. Waiting until the end to submit runs the risk of losing work (e.g., if you lose your internet connection or your session expires).

For some questions, the "calcPad" menu appears when you click in an answer box. This lets you enter mathematical expressions/formulas with special formatting and symbols. Here are a few examples to get you started, but this is not a complete list:

• To enter square root of 42:
  
  Keyboard: Type "sqrt" to generate the square root symbol, and then type "42". Do not enter the quotation marks. To move in or out of the square root, use the arrow keys on your keyboard or click in the appropriate place with your mouse.
  
  calcPad: Click on "Operations", select the square root symbol, and type "42".
  
  
• To enter vector 2i-3j:
  
  The "i" and "j" keys on the keyboard will not work for this purpose. Instead, type "2"; click on the "Vectors" menu and select "i"; type "-3"; and select "j" on the "Vectors" menu.
  
  Or you may use the other vector notation and just type an answer without using the calcPad menu: "(2,-3)" in 2D or "(2,-3,0)" in 3D. You have to use parentheses; it will not accept "<2,-3>" notation.
  
  
• The formula below may be entered using the keyboard only; using calcPad; or by intermixing these methods.
  
  
  Keyboard:
  Type "(1,pi,3)/". After hitting the slash, it goes into fraction mode and puts the cursor in the denominator.
  Type "sqrt" and it shows a square root symbol.
  Type "pi^2", which it will show in mathematical notation.
  To get out of the superscript, use the right or down arrow, or click in the appropriate position with your mouse.
  Type "+10".
  
  calcPad:
  Click on "Operations" and select the icon showing a fraction.
  Click on the top or bottom of the fraction to enter a value there.
  Click on the top. Type "(1,pi,3)". Or type "(1," and then click on "Greek" and select the pi symbol, then continue typing ",3)".
  Click on the bottom. Click on "Operations" and select square root.
  You may enter the denominator using the keyboard as described above, or continue using calcPad as described below.
  Select "Greek" and select the pi symbol.
  Click on "Operations" and select the icon of one box to the power of another box. Type "2" in the exponent.
  To get out of the subscript, use the right or down arrow, or click in the appropriate position with your mouse.
  Type "+10".

• Our textbook uses log(u) for natural logarithm instead of ln(u), so in WebAssign questions for our book, log(u) means natural log rather than log base 10. However, in answers that require a logarithm, WebAssign will accept both log(u) and ln(u) for natural log.
