\({\left(\tan \left(\log_* (1 + a)\right)\right)}^{\left(\log a \cdot \sinh a\right)}\)
  1. Started with
    \[{\left(\tan \left(\log_* (1 + a)\right)\right)}^{\left(\log \left({a}^{\left(\sinh a\right)}\right)\right)}\]
    0.1
  2. Applied taylor to get
    \[{\left(\tan \left(\log_* (1 + a)\right)\right)}^{\left(\log \left({a}^{\left(\sinh a\right)}\right)\right)} \leadsto {\left(\tan \left(\log_* (1 + a)\right)\right)}^{\left(\log a \cdot \sinh a\right)}\]
    0.0
  3. Taylor expanded around 0 to get
    \[{\left(\tan \left(\log_* (1 + a)\right)\right)}^{\color{red}{\left(\log a \cdot \sinh a\right)}} \leadsto {\left(\tan \left(\log_* (1 + a)\right)\right)}^{\color{blue}{\left(\log a \cdot \sinh a\right)}}\]

Original test:


(lambda ((a default) (b default) (c default))
  #:name "(pow (tan (log1p a)) (log (pow a (sinh a))))"
  (pow (tan (log1p a)) (log (pow a (sinh a)))))
