Most of the functions we study in elementary calculus are described by simple formulas. These functions almost always possess derivatives and, in fact, a portion of any first course in calculus is devoted to the development of routine methods for computing derivatives. However, not all functions ...
Two basic subjects, continuity and limits, in the first two sections in terms a high school student can understand, and continue with the theoretical considerations afterward.

To study continuity and differentiability of a function of two or more variables, we first need to learn some new terminology.Definition Let SS be a subset of R2R2 (Figure 4). A point P0P0 is called an interior point of SS if there is a δδ disk centered around P0P0 contained ...

Using again the Hausdorff convergence of Ω¯un and {u n = 0}, we get that, for n large enough, there are points y0∈Ω¯u0∩Uandz0∈{u0=0}∩U, such that |xn−y0|<εand|xn−z0|<ε. Now, by the continuity of u 0, we get that there is a point w 0 on ...

the reason the epsilon delta definition of continuity and limits is needed is so you can actually verify that certain limits exist. i.e. it gives you a concrete way to check the truth of what you are being told. you do not em to value that, but prefer to just believe what you are ...
When using the normal approximation to the binomial, we must apply the continuity correction. What is this and why do we need to use it?Plot the logistic response function:. What is the asymptote of this response function? For what value of X does the re...
In Mathematics, alimitis defined as a value that a function approaches the output for the given input values. Limits are important in calculus and mathematical analysis and used to define integrals, derivatives, and continuity. It is used in the analysis process, and it always concerns about th...
