Homework Statement
Consider a uniform surface charge density σ on a square of unit area.
(a) Compute the electrostatic potential Φ along the line normal to the center of the square.
My current attempt at a solution (image attached) is either incomplete or is simply wrong but I am unable to figure out where I went wrong. I am told the final answer involves an arc-coth (hyperbolic inverse cotangent) term and an inverse tangent term. I have one of those but not the other and I am now at a loss. Any help is highly appreciated thanks.
