Using differentials, give approximations for these quantities. (Show your work.)

  1. \( 1/(\sqrt{10} + 1) \)
  2. \( 3 + 4 \tan (\pi /12) \)

I like these problems because they give students a nice introduction into approximating values that are not easily accessible unless with the aid of a calculator. In addition, instructing students to interpret their computations on the graphs of these underlying functions, students get a nice geometrical perspective of linear approximations.
