WebFind the derivative of f ( x) = x ln ( x) . We set f ( x) = x and g ( x) = ln ( x). Then f ′ ( x) = 1, and g ′ ( x) = 1 x (check these in the rules of derivatives article if you don't remember them). Now use the product rule to find: d y d x = f ( x) g ′ ( … In mathematics, the interior product (also known as interior derivative, interior multiplication, inner multiplication, inner derivative, insertion operator, or inner derivation) is a degree −1 (anti)derivation on the exterior algebra of differential forms on a smooth manifold. The interior product, named in opposition to the exterior product, should not be confused with an inner product. The interior product is sometimes written as
