A unit circle is made up of n wedges equivalent to the inner wedge in the ?gure. The base of the inner triangle is 1 unit and its height is sin ( π n ) . The base of the outer triangle is B = cos ( π n ) + sin ( π n ) tan ( π n ) and the height is H = B sin ( 2 π n ) t Use this information to argue that the area of a unit circle is equal to π.
