The derivative of a functionfis an expression that tells you what the slope offis at any point in the domain off.The derivative offis a function itself. In this article, we will focus on the functions of one variable, which we will callx. However, when there are more variables, it wor...
We will now go through two examples step-by-step. How to Find the Derivative of a Function Using the Limit of a Difference Quotient: Example 1 Find the first derivative off(x)=2x−3. Step 1:Identify our function. The function that we are finding the first d...
The meaning of DERIVATIVE OF A FUNCTION is the limit if it exists of the quotient of an increment of a dependent variable to the corresponding increment of an associated independent variable as the latter increment tends to zero without being zero.

The derivative of a function is the ratio of the difference of function value f(x) at points x+Δx and x with Δx, when Δx is infinitesimally small. The derivative is the function slope or slope of the tangent line at point x. ...

For example, textbook examples to the contrary, the "derivative" (read: complex derivative) of the absolute value function does not exist because at every point in the complex plane, the value of the derivative depends on the direction in which the derivative is taken (so the Cauchy-Riemann ...
