Common Derivative Formulas and Rules

This page presents a comprehensive table of common derivative formulas and important rules for calculating derivatives of more complex functions.

Example: For f(x) = x², the derivative is f'(x) = 2x. This formula is applicable for all real numbers x.

The table includes derivatives of constant functions, linear functions, power functions, and root functions. It also covers the domains of definition and derivability for each function type.

Highlight: The derivative of xⁿ is nxⁿ⁻¹ for any real number n, except when n = 0.

The page introduces several important rules for calculating derivatives:

1. The derivative of a sum: (u(x) + v(x))' = u'(x) + v'(x)
2. The derivative of a constant multiple: (ku(x))' = ku'(x)
3. The product rule: (u(x)v(x))' = u'(x)v(x) + u(x)v'(x)

These rules are essential for calcul de dérivée étape par étape (step-by-step derivative calculation) of more complex functions.

Introduction to Derivatives and Rates of Change

This page introduces fundamental concepts related to derivatives, including the rate of change and derivative numbers. It also explains the equation of a tangent line to a curve.

Definition: The rate of change of a function f between points A and B is defined as the ratio of the change in y-values to the change in x-values: (yB - yA) / (xB - xA).

Vocabulary: The derivative number of a function f at a point x0 is the limit of the rate of change as h approaches zero: lim(h→0) [f(x0 + h) - f(x0)] / h.

The concept of derivatives is closely related to tangent lines. The slope of the tangent line at a point on the curve is equal to the derivative of the function at that point.

Highlight: The equation of the tangent line to the curve at point A(x0, f(x0)) is given by y = f'(x0)(x - x0) + f(x0), where f'(x0) is the derivative of f at x0.

The page includes a graph illustrating these concepts, helping students visualize the relationship between the function, its tangent line, and the derivative at a specific point.
