WebBasically, f is differentiable at c if f'(c) is defined, by the above definition. Another point of note is that if f is differentiable at c, then f is continuous at c. Let's go through a few examples and discuss their differentiability. … WebThe derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of the line tangent to the function's graph at that point. Learn how we define the derivative using limits. Learn about a bunch of very useful rules (like the power, product, and quotient …
Subtleties of differentiability in higher dimensions
WebIf f(x) is continuous at x = a, it does not follow that f(x) is differentiable at x = a.The most famous example of this is the absolute value function: f(x) = jxj = 8 >< >: x x > 0 0 x = 0 ¡x x < 0 The graph of the absolute value function looks like the line y … WebSep 12, 2024 · Differentiability: If ##f:ℝ^n\rightarrow ℝ^m## is differentiable at ##a\in ℝ^n##, then there exists a unique linear transformation such that ##\lim_{h\rightarrow 0} ...
