Gradient tells us how the field changes around a given
point
...


Level surfaces are also
called isosurfaces
...
g
...

It’s important to identify and analyze what happens with
the field around them because differentiation or
integration around them may fail!
For example gradient may not be defined there
...

 

 

What is the geometrical meaning of the divergence?
Patience!
 

 

Curl is the second of the two combinations of partial
derivatives which characterize the space variation of vector

 

What is the geometrical meaning of the curl? Patience!
Suppose I applied the del to some field, vector or scalar
...
Now if I apply the del to the new
field what will I get?
