OK. So I need a chart giving the values of Gradient, divergence, curl and the Laplacian in polar co-ordinates, as it is tremendously used when I am taking my course in electromagnetic theory. Please help

This is the one I give to my students.
For curl, change the French $\wedge$ for the English $\times$

@jango_IN_DTOWN yup, I know how you feel. and maybe SPHERICAL HARMONICS is another part of the "menu". http://perendis.webs.com

@Vincent-Lyon.Fr 
thanks for the list, it has Cartesian, cylindrical and spherical polar coordinates. 
But polar co-ordinates is missing.

osprey · Answer

by polar coordinates you mean PLANE polar coordinates, I take it ?

vincent-lyon.fr · Answer

You're welcome. Polar coordinates is the same as cylindrical coordinates.

@Vincent-Lyon.Fr Vous etes Francais, Monsieur ?

jango_in_dtown · Answer

@osprey yes plane polar
x= r cos theta, y=r sin theta

vincent-lyon.fr · Answer

plane polar and cylindrical are just two different names, but they are the same thing.
Usually, z is not mentioned in plane polar, but it is necessary as soon as you need a cross-product or a curl.
