1. 다음 셋이 특히 3D vector calculus에서 중요 ¶
| cartesian | cylindrical | spherical | |
| 좌표변수 | $\displaystyle x,y,z$ | $\displaystyle \rho,\phi,z$ | $\displaystyle r,\theta,\phi$ |
| 좌표의 범위 | $\displaystyle \begin{align}-\infty\lt & x\lt\infty\\-\infty\lt & y\lt\infty\\-\infty\lt & z\lt\infty\end{align}$ | $\displaystyle \begin{align}0\le&\rho\lt\infty\\0\le&\phi\le 2\pi\\-\infty\lt&z\lt\infty\end{align}$ | $\displaystyle \begin{align}0\le&r\lt\infty\\0\le&\theta\le\pi\\0\le&\phi\le 2\pi\end{align}$ |
Rationale
$\displaystyle x, y, z\in\mathbb{R}$ 은 당연.
$\displaystyle 0\le\rho,r\lt\infty$ : 반직선의 길이는 0 이상이므로 당연.
$\displaystyle 0\le\phi\le 2\pi$ : 각도이므로 당연.
