    • #16 Assignment

      Read 4.6
      On 40 may get derivative from graph, on all other problems you must show finding the derivative formula.
      4.6; 3, 7, 10, 18, 21, 33, 35, 38, 40.  
      p. 312; 76.
      On 76: Plot over 0 to 2 sec.  Measurements are positive going counterclockwise and negative going clockwise (as is usual in math).  So in d, positive acceleration corresponds to counterclockwise force.

    • #17 Assignment

      Read 5.1 & 5.2.
      5.1; 17+, 26+, 29+, 32+, 41, 44, 53, 56.
      The + means to also find (d) where a relative maximum is at x or relative minimum is at x.
      Hint on 17-32:  simplify y' by common denominator or factoring.
      Hint on 53 & 56:  The quadratic formula (p. R-13) can help find where derivative = 0.

    • #18 Assignment

      You must find maximums or minimums by using the derivative.
      5.2; 15, 42ab, 46, 50, 53 as specified below.
      Hint on 42b:  Include both + and - when you take a 6th root or ^(1/6).
      On 46b, do find the time but actual maximum value is optional.
      On 53:  On (b-i), I require you to use csc functions instead of sin as in back of book.  On (j-m), change to sin and factor out sin functions.  On m, consider at or near endpoints 0 and pi/2.  Throughout, try to avoid looking at the back of book unless necessary; it's fine if you "get ahead" of what they are asking on each step.
