    Understanding symmetry in electric field calculations

    Homework Statement Consider the specific case of a point above the axis of a circular ring of charge, how do the calculations follow to cancel the radial components? I understand the concept of the symmetry but don't understand how to express it in the expression without just removing the term...

    Electric field above a circular loop

    Could someone help me understand how the symmetry is expressed mathematically? I completely understand the symmetry of the situation conceptually but cannot see how to show it mathematically, I have reduced the electric field vector into its radial and axial components as in the following...
