\(\frac{a}{-{\left(\sqrt{\cos^{-1} a}\right)}^2}\)
  1. Started with
    \[\frac{a}{-\cos^{-1} a}\]
    0.3
  2. Using strategy rm
    0.3
  3. Applied add-sqr-sqrt to get
    \[\frac{a}{-\color{red}{\cos^{-1} a}} \leadsto \frac{a}{-\color{blue}{{\left(\sqrt{\cos^{-1} a}\right)}^2}}\]
    0.1
  4. Removed slow pow expressions

Original test:
