Continuity and DifferentiabilityA function is always continuous if it is differentiable at any point, whereas the vice-versa for this condition is not always true.Integral Calculus Integral calculus is the study of integrals and the properties associated to them. It is helpful in:...
This unique book provides a new and well-motivated introduction to calculus and analysis, historically significant fundamental areas of mathematics that are widely used in many disciplines. It begins with familiar elementary high school geometry and algebra, and develops important concepts such as ...
This discussion will be purely formal, in the sense that (important) analytic issues such as differentiability, existence and uniqueness, etc. will be largely ignored. Read the rest of this entry » PCM article: The Schrodinger equation 2 October, 2007 in Companion, math.AP, math.MP | Ta...
Twice differentiable isnothing but thedouble derivative double derivative The second derivative of a function f can beused to determine the concavity of the graph of f. A function whose second derivative is positive will be concave up (also referred to as convex), meaning that the tangent line...
is continuous. This example illustrates that everywhere differentiability is a significantly stronger property than almost everywhere differentiability. We will see further evidence of this fact later in these notes; there are many theorems that assert in their conclusion that a function is almost everywh...

Why is Differentiability Necessary? Functions that arecontinuousbut not differentiable everywhere on(a,b)(a,b)will either have a corner or a cusp somewhere in the inteval. When this happens, they might not have a horizontaltangent line, as shown in the examples below. ...
If f(z) is continuous at a point z_0 , show that \overline{f(z)} is also continuous at z_0 . Is the same true for differentiability at z_0 ? What does the function f(z) = z ^2 show? How about f(z) = z ? Let f...
