http://sintesis.ugto.mx/WintemplaWeb/01Neural%20Lab/00Introduction/06Weights%20Derivatives/index.htm In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to … See more If f is differentiable at a, then f must also be continuous at a. As an example, choose a point a and let f be the step function that returns the value 1 for all x less than a, and returns a different value 10 for all x greater than or … See more Let f be a function that has a derivative at every point in its domain. We can then define a function that maps every point x to the value of the derivative of f at x. This function is written f′ … See more Leibniz's notation The symbols $${\displaystyle dx}$$, $${\displaystyle dy}$$, and $${\displaystyle {\frac {dy}{dx}}}$$ were introduced by Gottfried Wilhelm Leibniz See more Vector-valued functions A vector-valued function y of a real variable sends real numbers to vectors in some vector space R … See more Let f be a differentiable function, and let f ′ be its derivative. The derivative of f ′ (if it has one) is written f ′′ and is called the second derivative of … See more The derivative of a function can, in principle, be computed from the definition by considering the difference quotient, and computing its limit. In practice, once the derivatives of a few simple functions are known, the derivatives of other functions are more easily … See more The concept of a derivative can be extended to many other settings. The common thread is that the derivative of a function at a point serves as a linear approximation of the function at that point. • An important generalization of the derivative concerns See more
