Put in f (x+Δx) and f (x): x2 + 2x Δx + (Δx)2 − x2 Δx. Simplify (x 2 and −x 2 cancel): 2x Δx + (Δx)2 Δx. Simplify more (divide through by Δx): = 2x + Δx. Then, as Δx heads towards 0 we get: = 2x. Result: the derivative of x2 is 2x. In other words, the slope at x is 2x. We write dx instead of "Δx heads towards 0".

Derivative, in mathematics, the rate of change of a function with respect to a variable. Geometrically, the derivative of a function can be ...

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 ...

In calculus, differentiation is one of the two important concepts apart from integration. Differentiation is a method of finding the derivative of a function. Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables.

If f is a differentiable function on ℝ (or an open interval) and x is a local maximum or a local minimum of f, then the derivative of f at x is zero. Points where f'(x) = 0 are called critical points or stationary points (and the value of f at x is called a critical value). If f is not assumed to be everywhere differentiable, then points at which it fails to be differentiable are also designated critical points.

Derivatives are named as fundamental tools in Calculus. The derivative of a moving object with respect to rime in the velocity of an object. It measures how often the position of an object changes when time advances. The derivative of a variable with respect to the function is the slope of tangent line neat the input value.
