STUDENTS BEWARE: Don't be a victim of JG's fake math
The initial responses to my New Calculus ...
When will YOU learn, Troll Boy?
JG here claims to have a discovered a shortcut to mastering calculus without using limits. Unfortunately for him, this means he has no workable a definition of the derivative of a function. It blows up for functions as simple f(x)=|x|. Or even f(x)=0. As a result, he has had to ban 0, negative numbers and instantaneous rates of change rendering his goofy little system quite useless. What a moron!
Forget calculus. JG has also banned all axioms because he cannot even derive the most elementary results of basic arithmetic, e.g. 2+2=4. Such results require the use of axioms, so he must figure he's now off the hook. Again, what a moron!
Even at his advanced age (60+?), John Gabriel is STILL struggling with basic, elementary-school arithmetic. As he has repeatedly posted here:
"There are no points on a line."
--April 12, 2021
"Pi is NOT a number of ANY kind!"
--July 10, 2020
"1/2 not equal to 2/4"
--October 22, 2017
“1/3 does NOT mean 1 divided by 3 and never has meant that”
-- February 8, 2015
"3 =< 4 is nonsense.”
--October 28, 2017
"Zero is not a number."
-- Dec. 2, 2019
"0 is not required at all in mathematics, just like negative numbers."
-- Jan. 4, 2017
“There is no such thing as an empty set.”
--Oct. 4, 2019
“3 <=> 2 + 1 or 3 <=> 8 - 5, etc, are all propositions” (actually all are meaningless gibberish)
--Oct. 22, 2019
No math genius our JG, though he actually lists his job title as “mathematician” at Linkedin.com. Apparently, they do not verify your credentials.
Though really quite disturbing, interested readers should see: “About the spamming troll John Gabriel in his own words...” (lasted updated March 10, 2020) at https://groups.google.com/forum/#!msg/sci.math/PcpAzX5pDeY/1PDiSlK_BwAJ
