  • Week 06: Sept. 27

    • Read 6.4 Example 2 only (for now).
      Read 4.4.
      I suggest the following unusual order of sections and problems.
      4.3; 56, 58, 62ab.
      6.4; 15, 18, 19, 13.  (13 is trickier than the other three.)
      4.4; 3, 8, 15, 21, 27.

    • Read 4.5.
      4.4; 41, 48, 60 as below, 67.
      4.5; 7, 14, 16, 23, 37, 57.
      Hints on 4.4; 48:  You may use calculator graph (y1(x) for V(t)) or Desmos to answer a,c,e.  On c, may find intersection with y=0.5.  On e, get value from graph (V'(240) in Desmos) but try symbolic derivative for practice (evaluation optional).
      On 4.4; 60: Just find I' for r=4,n=3, but leave the rest of the constants as letters; you don't have to do parts a and b.  This prepares you for the evaluations of parts a and b, but these are OPTIONAL and most easily done by typing the formula into some computing (TI-89 or Desmos) where you can specify constants (b=8) and evaluate at points.
