11/17
11/21 		  Read 9.1, 9.2, 9.3
  Do P9.3-1, and note errata on 9.3-1
 
  Hints: Note that in Table 9.3-1 on page 353 of
  your text, variable x2(t) is the one you will
  eventually leave in the differential equation, thus
  vc(t) plays the role of x2(t). In step two, for
  this problem consider a KVL equation around the
  outer loop. For step three, consider a KCL
  equation at the top right node. Manipulate
  that equation as needed to get it into the form
  iL(t) = . . .   and further manipulate it to the form
  diL(t)/dt = . . . Use both forms in step four as
  needed to eliminate iL(t) and diL(t)/dt from the
  step two equation.

11/14
11/21 		  Read 8.7, 8.8, Scan 8.9, 8.10
  Do P8.7-2, P8.7-4
 
  Note: On page 331 our texbook mentions
  MATLAB's "dsolve" function. This function is
  not supported on Dordt's version of MATLAB.
  The main point is that sometimes people use the
  symbol D instead of s to represent the
  differential operator.
 
  Hints for P8-7-2:
  1.) Let iL be the current downward through
       the inductor.
  2.) Consider initial conditions for iL and v at t = 0–
  3.) Consider initial conditions for iL and v at t = 0+
  4.) Write KCL at top right node, valid for t > 0.
       Use variables iL(t) and v(t).
  5.) Use the equation iL(t) = (1/L)∫v(t)dt to
       eliminate iL(t) from the KCL equation.
  6.) Differentiate both sides of the KCL equation
       and solve the resulting D.E. for v(t).

below 		  Scan Chapter 1 and
           Chapter 2 through Section 2.6.
  Review as necessary.
  You may also refer to the EGR 103 handout.
  (103 Handout available via courses@dordt here)
 
  Do P1.3-4, P1.6-2, P1.6-3, P2.5-7.
  Bring homework questions to class on Friday.

Note 1) Homework must be ready for peer grading and discussion in class on the first listed due date. It must be turned in for a final grade on the second listed due date. Peer grading will be 1/5 (20%) of the homework grade.

Note 2) If the "Returned" date is a link, then solutions are available in courses@dordt. If you click the link and get a login screen, use your usual courses@dordt login. Then use the back icon (or alt-left-arrow on the keyboard) twice to get back to the link and click it again. The link only works after you are logged in.

Note 3) Problems sets shown above with no "assigned" date are tentative. More problems might be added, expected due dates might change, but problems shown will eventually be assigned.

Note 4) If you are having difficulty reading the latest version of this page it may have to do with your browser's cached memory. Read this note on cached pages to solve the problem.

Note 5) Your textbook includes "Exercises" which are embedded within the chapters and "Problems" which are found at the end of each chapter. Items in the lists above that start with "P" are problems—look for them at the end of the chapter. Items that start with "Ex" are Exercises—look for them in the body of the chapter. Items that start with "VP" or "DP" are also found at the end of the chapter, after the "P" problems.
