polar coordinate

常見(jiàn)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(shuō)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
