For positive values of a and b, the binomial theorem with n = 2 is the geometrically evident fact that a square of side a b can be cut into a square of side a, a square of side b, and two rectangles with sides a and bWith n = 3, the theorem states that a cube of side a b can be cut into a cube of side a, a cube of side b, three a × a × b rectangular boxes, and three a × b × b. The general form of hn can be written as hn=A0δnc(5)ncos(φnθ) (4) Substituting (4) into (3) yields A0(δn2 6δn125δn)=2δn2 4δn1 Setting n=0 yields A0 =0 To determine c and θin (4), we need to find two values of hn (not initial conditions sice hn is defined in n 0, however, by using iterative procedure we can derive two auxiliary conditions h0 and h1).
