    if a < 1754.9059475022818

    1. Started with
      \[\cos^{-1} \left({\left(\left(\cosh a\right) \bmod \left(a \cdot a\right)\right)}^{\left(\log_* (1 + a)\right)}\right)\]
      60.5
    2. Applied simplify to get
      \[\color{red}{\cos^{-1} \left({\left(\left(\cosh a\right) \bmod \left(a \cdot a\right)\right)}^{\left(\log_* (1 + a)\right)}\right)} \leadsto \color{blue}{\cos^{-1} \left({\left(\left(\cosh a\right) \bmod \left({a}^2\right)\right)}^{\left(\log_* (1 + a)\right)}\right)}\]
      60.5
    3. Using strategy rm
      60.5
    4. Applied add-log-exp to get
      \[\cos^{-1} \left({\color{red}{\left(\left(\cosh a\right) \bmod \left({a}^2\right)\right)}}^{\left(\log_* (1 + a)\right)}\right) \leadsto \cos^{-1} \left({\color{blue}{\left(\log \left(e^{\left(\left(\cosh a\right) \bmod \left({a}^2\right)\right)}\right)\right)}}^{\left(\log_* (1 + a)\right)}\right)\]

      62.0
    3. Applied taylor to get
      \[\cos^{-1} \left({\left(\left(\cosh a\right) \bmod \left({a}^2\right)\right)}^{\left(\log_* (1 + a)\right)}\right) \leadsto \cos^{-1} \left({\left(\left(\cosh \left(\frac{1}{a}\right)\right) \bmod \left(\frac{1}{{a}^2}\right)\right)}^{\left(\log_* (1 + a)\right)}\right)\]
      31.6
