WebOct 23, 2008 · At a particular point, your field has components in the r-hat, phi-hat, and theta-hat directions. These three vectors constitute an orthonormal basis. So you simply take the cross product without any modification at all. For example, and the rest are similar. Suggested for: Cross Product Polar Coor WebCylindrical coordinates are defined with respect to a set of Cartesian coordinates, and can be converted to and from these coordinates using the atan2 function as follows. Conversion between cylindrical and Cartesian coordinates #rvy‑ec. x =rcosθ r =√x2 +y2 y =rsinθ θ =atan2(y,x) z =z z =z x = r cos θ r = x 2 + y 2 y = r sin θ θ ...
