Google Search is fair, balanced with Counterpoint for "Dan Christensen math" with showing that he is a failure of mathematics with never a geometry proof of Fundamental Theorem of Calculus. But then Dr. Terence Tao and Dr. Andrew Wiles need a fair, honest, balanced Google Search page where in the first page of the Google Search List shows them also a failures of Mathematics, and quite honestly, Tao, Wiles, Hales, Stillwell, Pipher, Ribet do not belong in math education nor mathematics period. None acknowledges that Calculus is geometry and therefore they are obligated to give a geometry proof of Fundamental Theorem of Calculus. (See AP's proof of 2013-2015, his geometry proof below.)

Failures of mathematics and logic like Dan Christensen belong in a asylum, not in the corridors of mathematics, especially in colleges and universities.

World's First Geometry Proof of Fundamental Theorem of Calculus// Math proof series, book 2 Kindle Edition
by Archimedes Plutonium (Author)

Last revision was 19May2021. This is AP's 11th published book of science.
Preface:
Actually my title is too modest, for the proof that lies within this book makes it the World's First Valid Proof of Fundamental Theorem of Calculus, for in my modesty, I just wanted to emphasis that calculus was geometry and needed a geometry proof. Not being modest, there has never been a valid proof of FTC until AP's 2015 proof. This also implies that only a geometry proof of FTC constitutes a valid proof of FTC.

Calculus needs a geometry proof of Fundamental Theorem of Calculus. But none could ever be obtained in Old Math so long as they had a huge mass of mistakes, errors, fakes and con-artist trickery such as the "limit analysis". To give a Geometry Proof of Fundamental Theorem of Calculus requires math be cleaned-up and cleaned-out of most of math's mistakes and errors. So in a sense, a Geometry FTC proof is a exercise in Consistency of all of Mathematics. In order to prove a FTC geometry proof, requires throwing out the error filled mess of Old Math. Can the Reals be the true numbers of mathematics if the Reals cannot deliver a Geometry proof of FTC? Can the functions that are not polynomial functions allow us to give a Geometry proof of FTC? Can a Coordinate System in 2D have 4 quadrants and still give a Geometry proof of FTC? Can a equation of mathematics with a number that is _not a positive decimal Grid Number_ all alone on the right side of the equation, at all times, allow us to give a Geometry proof of the FTC?
