(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

omega_c = (nabla) cross (u)

where

omega_c is the rotational velocity of a particle

nabla refers to the gradient operator

u is the linear velocity of the particle

2. Relevant equations

what are the expressions of

omega_c_x =

omega_c_y =

i.e, in x- and y-cordinates only.

3. The attempt at a solution

is it ??

omega_c_x = du_dy - du_dx;

omega_c_y = dv_dy - dv_dy;

sorry i have tried alot..beats me..pls help.
