In calculus, the Leibniz integral rule for differentiation under the integral sign, named after Gottfried Wilhelm Leibniz, states that for an integral of the form () (,), where < (), < and the integrands are functions dependent on , the derivative of this integral is expressible as (() (,)) = (, ()) (, ()) + () (,) where the partial derivative indicates that inside the integral, only the ...

The test was used by Gottfried Leibniz and is sometimes known as Leibniz's test, Leibniz's rule, or the Leibniz criterion. The test is only sufficient, not necessary, so some convergent alternating series may fail the first part of the test. [1] [2] [3] For a generalization, see Dirichlet's test. [4] [5] [6]
When substituted into the above formula, the Leibniz rule as applied for the standard exterior derivative and for the covariant derivative ∇ cancel out the arbitrary choice. [6] A vector-valued differential 2-form s may be regarded as a certain collection of functions s α ij assigned to an arbitrary local frame of E over a local coordinate ...
In calculus, the product rule (or Leibniz rule [1] or Leibniz product rule) is a formula used to find the derivatives of products of two or more functions.For two functions, it may be stated in Lagrange's notation as () ′ = ′ + ′ or in Leibniz's notation as () = +.
When taking the antiderivative, Lagrange followed Leibniz's notation: [7] = ′ = ′. However, because integration is the inverse operation of differentiation, Lagrange's notation for higher order derivatives extends to integrals as well. Repeated integrals of f may be written as
The integral of η V along a path is the work done against −V along that path. When n = 3 , in three-dimensional space, the exterior derivative of the 1 -form η V is the 2 -form d η V = ω curl V . {\displaystyle d\eta _{V}=\omega _{\operatorname {curl} V}.}
