Leibniz's Integral Rule: Also known as
Leibniz's Integral Rule is also referred to in some sources as Leibniz's Rule, but as this name is also used for a different result, it is necessary to distinguish between the two.
Other popular names for this technique include differentiation under the integral sign and Feynman's technique after physicist Richard Feynman.
Sources often refer to Leibnitz's Rule for Differentiation of Integrals or Leibnitz's Rule for Differentiation of an Integral or some such.
