polar coordinate

常見例句

This guy, you have two different ways of getting its polar coordinate equation.
有兩種辦法,可以得出極坐標(biāo)系下的方程。
Say, polar coordinates. Let's say that I have a function but is defined in terms of the polar coordinate variables on theta.
比如說極坐標(biāo)，有一個(gè)函數(shù),是根據(jù)極坐標(biāo)θ定義的。
And because you integrate first over r, well, first of all you should remember the polar coordinate formulas, namely x equals r cosine theta and y equals r sine theta.
這樣的話，我們就先對(duì)r積分，當(dāng)然了，首先得要記住坐標(biāo)轉(zhuǎn)換的公式，也就是x=rcosθ，y=rsinθ
