Formulae on the base vectors and the coordinate variables derivative going with fluid particle and their application;
因为标量与坐标系无关,故两个矢量的点积称为标量不变量。
Say, polar coordinates. Let's say that I have a function but is defined in terms of the polar coordinate variables on theta.
比如说极坐标,有一个函数,是根据极坐标θ定义的。
Strictly-speaking, if you are curious, we could also change to weird coordinate systems Jacobian using Jacobian with three variables at the same time.
为了满足大家的好奇心,严格来说,我们也可以换成其他各种坐标系,只需在变量替换时,使用。
