Derivative Calculator • With Steps!
www.derivative-calculator.netThe rules of differentiation (product rule, quotient rule, chain rule, …) have been implemented in JavaScript code. There is also a table of derivative functions for the trigonometric functions and the square root, logarithm and exponential function. In each calculation step, one differentiation operation is carried out or rewritten.
Differential of a function - Wikipedia
https://en.wikipedia.org/wiki/Differential_of_a_functionA consistent notion of differential can be developed for a function f : R → R between two Euclidean spaces. Let x,Δx ∈ R be a pair of Euclidean vectors. The increment in the function f is If there exists an m × n matrix A such that in which the vector ε → 0 as Δx → 0, then f is by definition differentiable at the point x. The matrix A is sometimes known as the Jacobian matrix, and the linear transformationthat associates to th…
Differentiable function - Wikipedia
https://en.wikipedia.org/wiki/Differentiable_functionA function of several real variables f: R → R is said to be differentiable at a point x0 if there exists a linear map J: R → R such that If a function is differentiable at x0, then all of the partial derivatives exist at x0, and the linear map J is given by the Jacobian matrix. A similar formulation of the higher-dimensional derivative is provided by the fundamental increment lemma found in single-variable calculus.
