Synopsis: 1. The fake foundations of mainstream mathematics. 2. Philosophical influence. We see how the foundations of mathematics are laid and also the rot of mainstream theory influenced by well-known deluded academics. ... https://www.youtube.com/watch?v=G90EEiT827c

A differential is simply a difference. A derivative is a fraction of differences. Given that fractions can be equivalent, we call dy and dx symbolic differentials meaning they can take on any value as long as dy/dx is an equivalent fraction so obtained. There is no such thing as an infinitesimal or infinity - both are junk concepts. To claim as do the ignorant fools of mainstream mathematics academia that dy = f'(x) dx is a definition for a differential is CIRCULAR, but this should not surprise because in their sewer brains there is a lot of circularity! :-) If Newton and Leibniz used angle for slope, then all smooth functions would have derivative functions whose ranges fall into the interval (-π/2, π/2) and vertical lines would have a slope.

The more I reveal new knowledge and publish truth, the more I am persecuted and hated. The truth is that I do know better than anyone else. Don't believe me!

"I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives." -Tolstoy What I showed in this video is the difference with how idiots mainstream math academics in their ignorance treat similar functions such the one described and their beloved absolute value function f(x)=|x|. They are so ignorant and stupid that they can't see outside their echo chambers. Don't emulate your idiot math professors and math teachers unless you too want to be an idiot like them.
