Euler Form

The term in the form of $r{e}^{i\theta }$ is referred to as the Exponential Form or sometimes called the Complex Exponential Form.

• It seems that it is not covered in Japanese high school mathematics?
  • When asked Japanese students, they said they didn’t know about it.
  • They don’t even learn Euler’s Formula… (mysterious) (takker)
    • I see. (blu3mo)
    • Instead, they try to express it using de Moivre’s Theorem.
      • Well, I didn’t want to go through all that trouble, so I wrote everything in $r{e}^{i\theta }$ form. (takker)
      • It might get complicated when teaching using Failure of Exponential and Logarithmic Laws. (blu3mo)
      • Ah! That makes sense! (takker)
        • By showing it in the form of $e^{\bullet }$, it may appear as if the logarithm can be applied to it.
        • So they are hiding it for that reason?
