In calculus, the product rule (or Leibniz rule 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 ( u ⋅ v ) ′ = u ′ ⋅ v + u ⋅ v ′ {\displaystyle (u\cdot v)'=u'\cdot v+u\cdot v'} or in Leibniz's notation as d d x ( u ⋅ v ) = d u d x ⋅ v + u ⋅ d v d x .
