Mamikon’s Theorem

(tangential approach to Mathematics)
Mamikon’s Theorem is the greatest advance in Calculus since the time of Newton. His theorem is the basis of what has become the discipline of Visual Calculus.
His theorem is that the area of the tangent sweep is equal to the area of the tangent cluster, regardless of the shape of the original curve.
