Calculus is false.

    • OP warned to not post "noise" again
    Calculus works for linear equations of the 1st order because it is simple geometry, and that cannot be faulted; one does not need calculus for this. Now take a second order equation, the simple function: y = x^2. From rudimentaries, detay y / deltax = 2x + delta x. That is the EXACT equation for the slope. One can make delta x as small as one wants, however the slope changes. Bringing delta x to infinity, and delta y follows, is the manner in which, all calculations are consistent, but not right. Infinity, as is well known, does not exist, for it is a mathematical trick for some aspects of mathematics to exist. Calculus is a manner in which, to normalise calculations throughout the mathematical and engineering field. Comments please.

    Are you familiar with epsilon-delta definitions which prove the correctness of the equations?

    Are you aware that there is ton of observational evidence for calculus?

    At least you could try to phrase your ideas coherently if you're trying to refute such a successful mathematical theory...

    Wow, Cruz! That is asking a lot. How can one hope phrase their ideas coherent when doing something fundamentally incoherent? It took a lot of guts for the OP just to put his thoughts up; it is too much to ask that they make sense too!

    I meant grammatical coherence :D

    To the OP: A lot of what you wrote was incorrect; in particular, your formulations for ##\frac{\Delta y} {\Delta x}## and your idea that we take ##\Delta x## to ##\infty##. Please do some research before making absurd statements about calculus "being false."
