Derivation

  1. Initial program 4.1

    \[\frac{\sin ky}{\sqrt{{\left(\sin kx\right)}^{2} + {\left(\sin ky\right)}^{2}}} \cdot \sin th\]

  2. Applied simplify2.6

    \[\leadsto \color{blue}{\frac{\sin th \cdot \sin ky}{\sqrt{\left(\sin ky\right)^2 + \left(\sin kx\right)^2}^*}}\]
  3. Using strategy rm

  4. Applied *-un-lft-identity2.6

    \[\leadsto \frac{\sin th \cdot \sin ky}{\color{blue}{1 \cdot \sqrt{\left(\sin ky\right)^2 + \left(\sin kx\right)^2}^*}}\]

  5. Applied times-frac0.2

    \[\leadsto \color{blue}{\frac{\sin th}{1} \cdot \frac{\sin ky}{\sqrt{\left(\sin ky\right)^2 + \left(\sin kx\right)^2}^*}}\]

  6. Applied simplify0.2

    \[\leadsto \color{blue}{\sin th} \cdot \frac{\sin ky}{\sqrt{\left(\sin ky\right)^2 + \left(\sin kx\right)^2}^*}\]
