KnowraRule of productLinked fromLinked fromThe 10 pages that link to Rule of product, each with the reason it gives.All 10Broader topic 2Related 5Narrower topic 1Compared with 2CombinatoricsRelated: It counts arrangements by splitting their construction into sequential choices.Chain ruleCompared with: It handles products of functions, while the chain rule handles nested function dependence.Differential calculusRelated: It shows how changing factors combine to change their product.Integration by partsNarrower topic: Integration by parts reverses this rule and rearranges its terms.Logarithmic differentiationCompared with: Taking logarithms converts products into sums, avoiding repeated applications of this rule.Second derivativeRelated: Differentiating a product twice uses the product rule and produces cross terms.Integrating factorRelated: The linear-equation method recognizes its left side as the derivative of μ(x)y.Combinatorial principlesBroader topic: It counts arrangements built through a sequence of decisions.Differentiation of trigonometric functionsRelated: It is needed when trigonometric functions appear multiplied by other functions.Differentiation rulesBroader topic: It accounts for both factors changing at once.
