\(\log \left(\frac{N + 1}{N}\right)\)
  1. Started with
    \[\log \left(N + 1\right) - \log N\]
    40.4
  2. Using strategy rm
    40.4
  3. Applied diff-log to get
    \[\color{red}{\log \left(N + 1\right) - \log N} \leadsto \color{blue}{\log \left(\frac{N + 1}{N}\right)}\]
    38.8

Original test:


(lambda ((N default))
  #:name "NMSE problem 3.3.6"
  (- (log (+ N 1)) (log N)))
