\(\frac{e^{x}}{(e^{x} - 1)^*}\)
  1. Started with
    \[\frac{e^{x}}{e^{x} - 1}\]
    40.4
  2. Applied simplify to get
    \[\color{red}{\frac{e^{x}}{e^{x} - 1}} \leadsto \color{blue}{\frac{e^{x}}{(e^{x} - 1)^*}}\]
    0.4

Original test:


(lambda ((x default))
  #:name "NMSE section 3.11"
  (/ (exp x) (- (exp x) 1))
  #:target
  (/ 1 (- 1 (exp (- x)))))
