cylindrical polar coordinates

基本解释

So, somehow they are more polar than cylindrical coordinates.
某種意義上，它比柱坐標更實用和流行一點。
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,柱坐標中z坐標還是，而x、y坐標，我們用R和θ來表示。
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.
柱坐標系就是，用平麪上的極坐標替換x和，即角θ和距離。
