Derivation

  1. Initial program 0.1

    \[\frac{e \cdot \sin v}{1 + e \cdot \cos v}\]

  2. Initial simplification0.1

    \[\leadsto \frac{e \cdot \sin v}{\cos v \cdot e + 1}\]
  3. Using strategy rm

  4. Applied flip-+0.1

    \[\leadsto \frac{e \cdot \sin v}{\color{blue}{\frac{\left(\cos v \cdot e\right) \cdot \left(\cos v \cdot e\right) - 1 \cdot 1}{\cos v \cdot e - 1}}}\]

  5. Applied associate-/r/0.1

    \[\leadsto \color{blue}{\frac{e \cdot \sin v}{\left(\cos v \cdot e\right) \cdot \left(\cos v \cdot e\right) - 1 \cdot 1} \cdot \left(\cos v \cdot e - 1\right)}\]

  6. Final simplification0.1

    \[\leadsto \frac{e \cdot \sin v}{\left(\cos v \cdot e\right) \cdot \left(\cos v \cdot e\right) - 1} \cdot \left(\cos v \cdot e - 1\right)\]
