\(\frac{0.5}{e^{im}} \cdot \sin re + \left(0.5 \cdot \sin re\right) \cdot e^{im}\)
  1. Started with
    \[\left(0.5 \cdot \sin re\right) \cdot \left(e^{0 - im} + e^{im}\right)\]
    0.1
  2. Using strategy rm
    0.1
  3. Applied distribute-lft-in to get
    \[\color{red}{\left(0.5 \cdot \sin re\right) \cdot \left(e^{0 - im} + e^{im}\right)} \leadsto \color{blue}{\left(0.5 \cdot \sin re\right) \cdot e^{0 - im} + \left(0.5 \cdot \sin re\right) \cdot e^{im}}\]
    0.1
  4. Applied simplify to get
    \[\color{red}{\left(0.5 \cdot \sin re\right) \cdot e^{0 - im}} + \left(0.5 \cdot \sin re\right) \cdot e^{im} \leadsto \color{blue}{\frac{0.5}{e^{im}} \cdot \sin re} + \left(0.5 \cdot \sin re\right) \cdot e^{im}\]
    0.1
