Visual calculus

Mamikon's theorem - the area of the tangent clusters are equal. Here the original curve with the tangents drawn from it is a semicircle.

Visual calculus, invented by Mamikon Mnatsakanian (known as Mamikon), is an approach to solving a variety of integral calculus problems.[1] Many problems that would otherwise seem quite difficult yield to the method with hardly a line of calculation. Mamikon collaborated with Tom Apostol on the 2013 book New Horizons in Geometry describing the subject.
