material covered on Wed 11/24: Complex numbers, summary and exercises
The lowest of the four exam scores will be weighted only 50% when I compute the average of the exam scores at the end of the semester:
average = [(sum of three highest scores) + 0.5*(lowest score)]/3.5.
Programs for trapezoid and Simpson rule for TI calculators
Exam 4 was on December 3. average=55, median=52.
25% of the students have score≥68, 50% have score≥52, 75% have score≥42.
Exam 3 was on November 5. average=59, median=59.
25% of the students have score≥72, 50% have score≥59, 75% have score≥48.
Early warning grades were based on exam 1 (70%), homeworks (15%, lowest 2 dropped), quizzes (15%, lowest quiz dropped). A total percentage ≥90%, ≥80;%, ≥70%, ≥60%, <60% corresponds to grades A, B, C, D, F, respectively.
Exam 2 was on October 15. average=82, median=86.
25% of the students have score≥94, 50% have score≥86, 75% have score≥58.
Exam 1 was on September 20: average=76, median=78.
25% of the students have score≥88, 50% have score≥76, 75% have score≥66.

WebAssign

You access WebAssign via www.webassign.net/umd/login.html using your official UMD directoryID and password.

The first 10 days of a class are free on WebAssign. If you consider dropping the course you should wait until the end of that period to register.

Instructions for WebAssign (Payment etc.)

WebAssign homeworks are due every Tuesday and Thursday at 8:00am, starting Sept. 2.

You have three tries for each question. You can see the number of submissions (used/possible) for each question if you click on the "+" to the right of the problem number along with the points earned for each question.
However, if a question is a multiple choice with only 2 or 3 choices, the grading is set up so that you can't just guess and get points for the question. For a two-choice answer (e.g., Converges or Diverges), you lose 100% of the points after 1 submission. For a 3-choice answer, that happens after 2 submissions.

Note the difference between Numerical Answer Boxes and Symbolic Answer Boxes:

How to tell the difference:
If the problem says "exact value" or there appears "symbolic formatting help" below it is a symbolic answer box. Also boxes where you can use mathPad accept symbolic answers.
In a symbolic answer box you can use variables (like x) and functions (like sin(x)). You can enter powers by typing "^" or by using mathPad.
In a numerical answer box you cannot use variables or functions (like sin). You can use + - * / and parentheses. You MUST use ** for powers, you cannot use "^". You cannot use sqrt, but you can use **(1/2).
Rule for entering powers (like 3^1/2): In an answer box without mathPad always use **, never ^, e.g., 3**(1/2).

WebAssign is picky:

You need to type in "dx" in integrals, and use parentheses in front of "dx" when necessary, e.g., "(3+x)dx".
For indefinite integrals your answer must contain "+C" with a capital letter C
