Method to calculate the area of a cyclic n-gon The area of a cyclic quadriateral, given the side lengths, is given as follows: $$ \sqrt{(s-a)(s-b)(s-c)(s-d)} $$ (Brahmagupta's formula) Where \$ s = \frac{a+b+c+d}{2}. \$ I want to find a similar expression, or a way of formulating an expression for a cyclic \$n-gon\$ given it's s...
