Elementary rules of differentiation[edit]
Unless otherwise stated, all functions are functions of real numbers (R) that return real values; although more generally, the formulae below apply wherever they are well defined^{[1]}^{[2]} — including the case of complex numbers (C).^{[3]}
Differentiation is linear[edit]
For any functions and and any real numbers and , the derivative of the function with respect to is
In Leibniz's notation this is written as:
Special cases include:
 The sum rule
 The subtraction rule
The product rule[edit]
For the functions f and g, the derivative of the function h(x) = f(x) g(x) with respect to x is
In Leibniz's notation this is written
The chain rule[edit]
The derivative of the function is
In Leibniz's notation, this is written as:
often abridged to
Focusing on the notion of maps, and the differential being a map , this is written in a more concise way as:
The inverse function rule[edit]
If the function f has an inverse function g, meaning that and , then
In Leibniz notation, this is written as
Power laws, polynomials, quotients, and reciprocals[edit]
The polynomial or elementary power rule[edit]
If , for any real number then
When this becomes the special case that if then
Combining the power rule with the sum and constant multiple rules permits the computation of the derivative of any polynomial.
The reciprocal rule[edit]
The derivative of for any (nonvanishing) function f is:
 wherever f is nonzero.
In Leibniz's notation, this is written
The reciprocal rule can be derived either from the quotient rule, or from the combination of power rule and chain rule.
The quotient rule[edit]
If f and g are functions, then:
 wherever g is nonzero.
This can be derived from the product rule and the reciprocal rule.
Generalized power rule[edit]
The elementary power rule generalizes considerably. The most general power rule is the functional power rule: for any functions f and g,
wherever both sides are well defined.^{[4]}
Special cases
 If , then when a is any nonzero real number and x is positive.
 The reciprocal rule may be derived as the special case where .
Derivatives of exponential and logarithmic functions[edit]
the equation above is true for all c, but the derivative for yields a complex number.
the equation above is also true for all c, but yields a complex number if .
Logarithmic derivatives[edit]
The logarithmic derivative is another way of stating the rule for differentiating the logarithm of a function (using the chain rule):
 wherever f is positive.
Logarithmic differentiation is a technique which uses logarithms and its differentiation rules to simplify certain expressions before actually applying the derivative. Logarithms can be used to remove exponents, convert products into sums, and convert division into subtraction — each of which may lead to a simplified expression for taking derivatives.
Derivatives of trigonometric functions[edit]
It is common to additionally define an inverse tangent function with two arguments, . Its value lies in the range and reflects the quadrant of the point . For the first and fourth quadrant (i.e. ) one has . Its partial derivatives are
, and 
Derivatives of hyperbolic functions[edit]
Derivatives of special functions[edit]
with being the digamma function, expressed by the parenthesized expression to the right of in the line above. 

Derivatives of integrals[edit]
Suppose that it is required to differentiate with respect to x the function
where the functions and are both continuous in both and in some region of the plane, including , and the functions and are both continuous and both have continuous derivatives for . Then for :
This formula is the general form of the Leibniz integral rule and can be derived using the fundamental theorem of calculus.
Derivatives to nth order[edit]
Some rules exist for computing the nth derivative of functions, where n is a positive integer. These include:
Faà di Bruno's formula[edit]
If f and g are ntimes differentiable, then
where and the set consists of all nonnegative integer solutions of the Diophantine equation .
General Leibniz rule[edit]
If f and g are ntimes differentiable, then
