The study demonstrates that graphic instructional representations for functions and their derivatives, and students' concomitant images, have the potential for producing a richer understanding than that achieved by analytic study alone. Stimulated by graphic instructional representations, students form and can...
Limits are played a crucial role in calculus and mathematical analysis, and they are used to define important concepts such as continuity, derivatives, and integrals. It also has practical applications in fields such as physics and engineering. Extended Definition of Limit: Epsilon-Delta Approach The...
This study reports the second research cycle on students’ understanding of directional derivatives of two-variable functions. We applied Action-Process-Object-Schema (APOS) Theory as theoretical framework as in the first cycle. As a result of the first research cycle, a refined genetic decomposition...

Like all things in life, there are varying levels of comprehension of calculus which could be deemed sufficient for differing depths of neural networks understanding. You could, for instance, feel justified in possessing a basic intuition of derivatives and an understanding of how backpropagation work...
, n times, we were able to express f(x) in terms of its n derivatives evaluated at a point a with the last terms being evaluated at some point c, between a and x. The series took the form: Taylor.s Theorem thus states: The important point to realize here is that n stands for ...
Instead of multiplication, the interaction is taking a partial derivative. As before, thei→component of curl is based on the vectors and derivatives in thej→andk→directions. Relation to the Pythagorean Theorem The cross and dot product are like the orthogonal sides of a triangle: ...
(Assuming $F_x$ is the field in the x-direction.) A few remarks: The symbol for divergence is the upside down triangle forgradient(called del) with a dot [$\triangledown \cdot$]. The gradient gives us the partial derivatives $(\frac{\partial}{\partial x}, \frac{\partial}{\partial...
Our introductory study of Calculus ends with a short but important study of series. The special type of series known as Taylor series, allow us to express any mathematical function, real or complex, in terms of its n derivatives. The Taylor series can also be called a power series as each...
