Twice-differentiable simply means that the function can be differentiated twice. eg. If y = x^5 (^5 means to the power of 5). Then y' = 5x^4 (i.e. differentiating once) Then y'' = 20x^3 (differentiating twice)
No.
In basic terms, Calculus is Differentiation and Integration And all things associated with that.
In its simplest form, l'Hôpital's rule states that for functions f and g which are differentiable on I\ {c} , where I is an open interval containing c:If, and exists, and for all x in I with x ≠ c,then.^from wiki
I don't think such a term is used in calculus. Check the spelling. Perhaps you mean point of inflection?

Definition: A function f is differentiable at a if f'(a) exists. it is differentiable on an open interval (a, b) [or (a, ∞) or (-∞, a) or (-∞, ∞)]if it is differentiable at every number in the interval.Example: Where is the function f(x) = |x| differentiable?Answer:1. f is differentiable for any x > 0 and x < 0.2. f is not differentiable at x = 0.That's mean that the curve y = |x| has not a tangent at (0, 0).Thus, both continiuty and differentiability are desirable properties for a function to have. These properties are related.Theorem: If f is differentiable at a, then f is continuous at a.The converse theorem is false, that is, there are functions that are continuous but not differentiable. (As we saw at the example above. f(x) = |x| is contionuous at 0, but is not differentiable at 0).The three ways for f not to be differentiable at aare:a) if the graph of a function f has a "corner" or a "kink" in it,b) a discontinuity,c) a vertical tangent
Calculus in some contexts means stone (such as a urinary calculus or salivary calculus), or can mean mineral deposits on teeth.A calculus, in medicine, is a stone that grows in some organs - such as a kidney.

The signum function, also known as the sign function, is not differentiable at zero. This is because the derivative of the signum function is not defined at zero due to a sharp corner or discontinuity at that point. In mathematical terms, the signum function has a derivative of zero for all values except at zero, where it is undefined. Therefore, the signum function is not differentiable at zero.
MVT stands for "Mean Value Theorem," a fundamental concept in calculus. It states that if a function is continuous on a closed interval and differentiable on the open interval, there exists at least one point where the instantaneous rate of change (the derivative) equals the average rate of change over that interval. This theorem is useful for understanding the behavior of functions and for proving other mathematical results.
If you mean "who invented calculus", then Isaac Newton and Gottfried Leibniz both developed it independently.
If y is a differentiable function of u, and u is a differentiable function of x. Then y has a derivative with respect to x given by the formula : dy/dx = dy/du. du/dx This formula is known as the Chain Rule and says, " The rate of change of y with respect to x is the rate of change of y with respect to u multiplied by the rate of change of u with respect to x."
The tangent function, ( \tan(x) ), is not differentiable everywhere. It is differentiable wherever it is defined, which excludes points where the function has vertical asymptotes, specifically at ( x = \frac{\pi}{2} + k\pi ) for any integer ( k ). At these points, the function approaches infinity, leading to a discontinuity in its derivative. Thus, while ( \tan(x) ) is smooth and differentiable in its domain, it is not differentiable at the points where it is undefined.
