The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists. More generally, a function is said to be differentiable on S if it is ...

WebbDid you mean the derivative of ln(u)? Because the derivative of ln(x) is 1/x, if we have the derivative of ln(u), where u is some polynomial, then we must use u-substitution, which says that d/dx[f(g(x))] = f'(g(x))*g'(x) If we do that for our ln expression, we get: d/dx[ln(u)] … Webb9 maj 2016 · 1 Answer sente May 9, 2016 The function, as given, is not continuous at 0 as 0sin( 1 0) is not defined. However, we may make a slight modification to make the function continuous, defining f (x) as f (x) = {xsin(1 x) if x ≠ 0 0 if x = 0 We will proceed using this modified function.
