Homework Statement Discuss the continuity and differentiability of f(x) = \begin{cases} x^2 & \text{if } x\in \mathbb{Q} \\ x^4 & \text{if } x\in...
Limits and continuity of piecewise functions. In each case, provide a specific value for a (and a specific value for b, when appropriate) to ensure that each piecewise-defined function is continuous at x=1. The " a " in one prob...
gradient descent algorithms can optimize neural networks that are sub-differentiable in their parameters; however, this implies that the neural network's activation function must exhibit a degree of continuity which limits the neural network model's uniform approximation capacity to continuous functions. ...
continuity. One day (approximately 50 minutes) Problems 1 through 6 Students need a strong foundation in all types of functions for the work to come in this and future math courses, especially calculus. This introduction to piecewise functions facilitates the students’ ability to work with ...
I like thinking of practical examples of things that I learn in my analysis course. I have been thinking about functions fn:[0,1] --->R. What is an...

Let’s graph it and see:It's obvious that the problem is at x=0. The first thing to check is that the function is actually continuous there, which means that limx→0f(x)=f(0). We can’t have differentiability with-out continuity.limx→0−f(x)=limx→0−(1)=1 limx→0+f...

Discussion on the relation between segmented functions and primary functions; 对分段函数与初等函数关系的讨论 2. Based on the discussion about an problem in teaching material,we propose methods of judging the extreme valuable points of segmented function. 首先对一例现行教材中的题解提出了疑问,给出...
Define functions Nin(u), called B-splines by defining their de Boor ordinates to satisfy di = 1 and dj = 0 for all j≠ i. The Nin(u) are clearly elements of the linear space formed by all piecewise polynomials over [un–1, uL]. They have local support: Nin(u)≠0 only...
