WebFunction f is differentiable at (x , y ). 0 0 0 Remark: A simple suﬃcient condition on a function f : D ⊂ R2 → R guarantees that f is diﬀerentiable: Theorem If the partial derivatives f x and f y of a function f : D ⊂ R2 → R are continuous in an open region R ⊂ D, then f is diﬀerentiable in R. Theorem In mathematics, a differentiable function of one real variable is a function whose derivative exists at each point in its domain. In other words, the graph of a differentiable function has a non-vertical tangent line at each interior point in its domain.
