cylindrical polar coordinates

基本解釋

So, somehow they are more polar than cylindrical coordinates.
某種意義上，它比柱坐標(biāo)更實(shí)用和流行一點(diǎn)。
OK, so you know about cylindrical coordinates z where we have the z coordinates stay z, and the xy plane we do R and theta polar coordinates.
我們知道,柱坐標(biāo)中z坐標(biāo)還是，而x、y坐標(biāo)，我們用R和θ來(lái)表示。
And cylindrical coordinates only mean that we are, instead of x, y and z, y we are replacing x and y by the polar coordinate in the x, y plane, r so the angle theta and the distance r.
柱坐標(biāo)系就是，用平麪上的極坐標(biāo)替換x和，即角θ和距離。
