Exercise 1.7

• Although this exercise does not require the writing of code, you will express your solution using Scheme definitions.

• For part a, suppose that puzzle1 computes the decimal expansion of π to 100 places (of course, it does not). Then you would express your answer as:

      (define 1.7a "puzzle1 computes the decimal expansion of pi to 100 places")

• Similarly, for part b, express your answer as:

      (define 1.7b "puzzle2 computes ...")

• The test file displays your answers by evaluating

      1.7a

  and

      1.7b
