What is the right formula for calculating the curl in spherical polar coordinates ??

dear it's best for remembering for all formulas.... this trick write in ur notes... it's very helpful...... see attached file

dear see general formula as well as in coordinate system as well

formula for curl in both spherical polar coordinates and cylindrical coordinates. remember these formulas in determinant form, as it is easy to remember.

this is curl in cylinderical coordinate

I attached formulas for curl in both spherical polar coordinates and cylindrical coordinates. Remember these formulas in determinant form. it is easy to remember.

this is the curl of vector in spherical coordinate.
