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. https://en.wikipedia.org/wiki/Visual_calculus Visual calculus - Wikipedia -- Client: 0E326822076E205F Received: 1707807364 Cookie: F8BB78CF94043367
