This category contains pages concerning Product Rule for Derivatives:
Let $\map f x, \map j x, \map k x$ be real functions defined on the open interval $I$.
Let $\xi \in I$ be a point in $I$ at which both $j$ and $k$ are differentiable.
Let $\map f x = \map j x \map k x$.
Then:
- $\map {f'} \xi = \map j \xi \map {k'} \xi + \map {j'} \xi \map k \xi$
It follows from the definition of derivative that if $j$ and $k$ are both differentiable on the interval $I$, then:
- $\forall x \in I: \map {f'} x = \map j x \map {k'} x + \map {j'} x \map k x$
