Natural Logarithm

There is a unique positive number e such that the function f (t) = e^t is its own derivative. The natural logarithm of a positive real number x is the logarithm of x with base e, denoted log(x). Alternately,

log(x) =
Chain Rule

The formula for the derivative of a composition of functions. If h(x) = fog(x) = f (g(x), then:

h'(x) = f'(g(x))g'(x).
Implicit Differentiation

A method for differentiating implicit functions, without necessarily solving for them, by differentiating the terms of the defining equation.
Product Rule

The formula for the derivative of a product of functions:

[f (x)g(x)] = f (x)g'(x) + g(x)f'(x)
Quotient Rule

The formula for the derivative of a quotient of functions (which is a consequence of the product rule). If q(x) = f (x)/g(x), then:

q'(x) =
