雙語使用場景

So, that's cosine theta d theta. And, well, if you do things with substitution, which is the way I do them, then you should worry about /2 the bounds for theta which will be zero to pi over two.───所以dx=cos,θdθ,如果用變量替換法來做,接下來就要考慮θ的取值范圍,它是從0取到π

So if we want to talk about the volume of that, we just talk about the surface area, which is 4 pi r squared, and we multiply that by the thickness d r.───如果我們要討論它的體積,我們要用的是表面面積,也就是4πr的平方,乘以厚度dr

perfectly spherical shell dr at some distance, thickness, d r, dr we talk about it as 4 pi r squared d r, so we just multiply that by the probability density.───在某個地方的完美球型殼層,厚度,我們把它叫做4πr平方,我們僅僅是把它,乘以概率密度。
