Hey is there any easy method to remember the relations for calculating
curl,divergence etc in various coordinate systems......??

I think the most effective method is to write them down
a hundred times :-)

Another method:
(1) Memorize the operators in curvilinear coordinates:
http://164.8.13.169/Enciklopedija/math/math/c/c863.htm
at the bottom of which you find a list of pointers to a bunch
of curvilinear coordinates, where you find the scale factors
for step (2)

(2) Memorize some scale factors. For instance:
Spherical:
http://164.8.13.169/Enciklopedija/math/math/s/s571.htm
Cylindrical:
http://164.8.13.169/Enciklopedija/math/math/c/c909.htm
Etc...

(3) Insert the scale factors of (2) in the expressions of (1).

Nice exercise :-)
