\(\frac{a}{1} \cdot \tan c - \sqrt{b^2 + b^2}^*\)
  1. Started with
    \[\frac{a}{\cot c} - \sqrt{b^2 + b^2}^*\]
    0.2
  2. Using strategy rm
    0.2
  3. Applied cotan-tan to get
    \[\frac{a}{\color{red}{\cot c}} - \sqrt{b^2 + b^2}^* \leadsto \frac{a}{\color{blue}{\frac{1}{\tan c}}} - \sqrt{b^2 + b^2}^*\]
    0.2
  4. Applied associate-/r/ to get
    \[\color{red}{\frac{a}{\frac{1}{\tan c}}} - \sqrt{b^2 + b^2}^* \leadsto \color{blue}{\frac{a}{1} \cdot \tan c} - \sqrt{b^2 + b^2}^*\]
