Jan 24, 2015 · A continuously differentiable function f(x) is a function whose derivative function f ′ (x) is also continuous at the point in question. In common language, you move the secant to form a tangent and it may give you a real tangent at that point, but if you see the tangents around it, they will not seem to be approaching this tangent in any ...
Aug 1, 2015 · 2. There is a general theory of differentiation for functions between two normed space. However, you may be happy to learn that a function f: Rn → Rm is continuously differentiable if and only if each component fi: Rn → R is continuously differentiable, for i = 1, …, m. Share.
Recall the 3-part definition of " f(x) f (x) is continuous at x = a x = a " from elementary calculus: 1. f(a) f (a) is defined. 2. limx→a f(x) lim x → a f (x) exists. 3. limx→a f(x) = f(a) lim x → a f (x) = f (a) Suppose the #2 holds and let's consider the possibilities. If #1 also holds, then either #3 holds or #3 doesn't hold.
Aug 17, 2015 · 1. The other replies offer great explanations for how the formula is generated and e's purpose, but this is the simple formula you will use for interest that is compounded continuously: A = Pert A = P e r t. Where A is Amount, P is Principal (money down), e is a constant (~2.718281828), r is rate, and t is time.
$\begingroup$ @user135626: What I wrote is correct. You are misreading it. I'm not saying the derivative is zero, I'm saying that if the derivative exists, the numerator of the difference quotient necessarily converges to zero (not that the difference quotient itself must).
