# Thread: Mathnerd vs John Gabriel: the filibustering crank

No one is laughing at you moron! We're used to your incoherent mathobabble. Care to tell us why Grapes is on your ignore list? Chuckle. He realised you are a moron bigger than he is.

The derivative in calculus applies to curvature - Newton was trying to explain variations in planetary orbits, along with Kepler, after all .. Newton's law of gravity is an inverse square law relating mass to radius of an orbit - Note: it actually gets more complicated...

John Gabriel (barely and only occasionally) manages to work out that the derivative of a straight line y = f(x) = Ax + b is the constant A for any point on the line.

f'(x) = A (independent of x, and therefore dx)

Infinitesimal calculus solves problems relating to non-linear functions (i.e., curvature).. which he rejects (along with , e, and complex numbers as having no relevance in his world (which is primarily good for counting change at McDonald's)...

His ignorance comes from trying to teach calculus to himself without understanding Analytic Geometry (which is its foundation). John Gabriel desperately needs to take (and pass) pre-calculus courses at a junior college somewhere .... As of now, I don't think he can post a GPA from anywhere.

Analytic Geometry

(The ticks on the axes appear as integers, but the spaces between them are filled by real numbers, at least some of which come from projecting trigonometric functions onto the axes)..

"In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Informally, it is a line through a pair of infinitely close points on the curve. More precisely, a straight line is said to be a tangent of a curve y = f(x) at a point x = c on the curve if the line passes through the point (c, f(c)) on the curve and has slope f'(c) where f' is the derivative of f. A similar definition applies to space curves and curves in n-dimensional Euclidean space."

I don't think sooooo.

See the original post in "John Gabriel's New Derivative" is toast"..

Don't worry, he's actively spamming them all quite eagerly now.

you do sound like mathnerd, the liar, why?

Why you never disagree with him?

Listen liar, I gave you an order: you must disagree with mathnerd. Why did you not obey the order?

This comment is a complete rebuttal of all the lies and ignorance being posted by Chuck Keyser (BuleriaChk) and mathnerd.

Watch Keyser dig himself way over his head.

Keyser making a fool of himself:

Pangalang lang pangalang langa lang lang.

Watch mathnerd struggling with basic algebraic concepts.

John Gabriel can (almost) calculate the slope of a straight line...
