The derivative of a function is one of the basic concepts of mathematics. Together with the integral, derivative occupies a central place in calculus.

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 ...

The instantaneous rate of change of a function f(x) at a value a is its derivative f′(a). Example 3.1.9: Chapter Opener: Estimating Rate of ...

A vector-valued function y of a real variable sends real numbers to vectors in some vector space R . A vector-valued function can be split up into its coordinate functions y1(t), y2(t), ..., yn(t), meaning that y(t) = (y1(t), ..., yn(t)). This includes, for example, parametric curves in R or R . The coordinate functions are real valued functions, so the above definition of derivative applies to them. The derivative of y(t) is defined to be the vector, called the tangent vector, whose coordinates are the …

Jun 04, 2018 · Here is a set of practice problems to accompany the The Definition of the Derivative section of the Derivatives chapter of the notes for Paul Dawkins Calculus I course at Lamar University.

The definition of the derivative is the slope of a line that lies tangent to the curve at the specific point. The limit of the instantaneous rate of change ...

What Is A derivative?

The definition of the total derivative subsumes the definition of the derivative in one variable. That is, if f is a real-valued function of a real variable, then the total derivative exists if and only if the usual derivative exists. The Jacobian matrix reduces to a 1×1 matrix whose only entry is the derivative f′(x).

May 30, 2018 · Section 3-1 : The Definition of the Derivative. In the first section of the Limits chapter we saw that the computation of the slope of a tangent line, the instantaneous rate of change of a function, and the instantaneous velocity of an object at \(x = a\) all required us to compute the following limit.
