Differentiable vs. Non-differentiable Functions - Calculus

WebTake x^2. First derivative at 0 is 2*0, which is 0, but its second derivative is just a constant 2, so at x=0 the constant equation 2 is 2 everywhere. Another way to look at it is the first derivative tells if the slope is 0, and the second derivative will tell if the original function is at an inflection point. Webgeometrically, the function f is differentiable at a if it has a non-vertical tangent at the corresponding point on the graph, that is, at (a,f (a)). That means that the limit. lim x→a f (x) − f (a) x − a exists (i.e, is a finite number, which is the slope of this tangent line). When this limit exist, it is called derivative of f at a and ... git push head:refs/for
