(S. 207, Bronstein)

• Polar
  $$\left ( \begin{array}{c} x \\ y \\ \end{array} \right ) = \left (\begin{array}{c} r \cos \varphi \\ r \sin \varphi \\ \end{array} \right )$$

• Kugel
  $$\left ( \begin{array}{c} x \\ y \\ z \\ \end{array} \right ) =... ...heta \\ r \sin \varphi \cos \theta \\ r \cos \theta \\ \end{array} \right )$$
