I saw this question asking about calculating monosymmetry index of an unequal angle. What I need is a formula to calculate $\int v_i{(u_i}^2 + {v_i}^2)\text{d}A$, given the depth $d$, breadth $b$ and thickness $t$ of an angle. $A$ is the area and $v$ and $u$ are the coordinates of each small element $i$ of the section. Is there a simplified method to derive the above, neglecting root radius and toe radius?
