Determine formula of area of n-sided polygon as function
An n-sided regular polygon is inscribed in a circle of radius R. Using triangles to construct the polygon and an appropriate double-angle formula, determine the formula of the area of the n-sided polygon as a function of R and n, i.e., A = f(R,n).
