Definition of differentiability

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 …

Actually, differentiability at a point is defined as: suppose f is a real function and c is a point in its domain. The derivative of f at c is defined by \(\lim\limits_{h \to 0} \frac{f(x+h) – f(x)}{h}\) Differentiability in interval: For open interval:
