通常还有一种方式,就是极坐标polar coordinates,在物理书籍中尤其常见 2.3.1 Vector as a Sequence of Displacements 向量作为一系列位移 一种更好理解向量就是位移displacement的方式是:将位移其分解到各个轴向上。当把这些轴向上各自的位移结合起来时,就得到了整个向量的位移 举个例子,向量[1,-3,4]表示一段位移...
You can read how to convert them at Polar and Cartesian Coordinates, but here is a quick summary:From Polar Coordinates (r,θ) to Cartesian Coordinates (x, y) From Cartesian Coordinates (x, y) to Polar Coordinates (r,θ) x = r× cos( θ ) y = r× sin(θ ) r = √ ( x2 ...
OD(3D) can be defined in polar coordinates (phi, theta, radius); always being equal to one, radius can be ignored. Easier handling of unitary optical density 2D vectors (OD(2D)) is shown. OD(2D) pure stains used in anatomical pathology were assessed as centroid values (phi, theta) ...
Student understanding of unit vectors and coordinate systems beyond cartesian coordinates in upper division physics courses This thesis constitutes an investigation into student understanding of concepts in thermal physics in an introductory calculus-based university physics course. Nearly 90% of students enro...

The collection of mathematical tools handles vectors, matrices, complex number, quaternion, coordinates, intersections and function plotting (polar plot,2D,3D). Statistic, dataanalysis, FFT, best fit.
In these systems, coordinates are defined by a set of curves or surfaces rather than straight lines, as in Cartesian coordinates. Examples of curvilinear coordinate systems include polar coordinates, cylindrical coordinates, and spherical coordinates....
