differentiable

adj

1. (not-comparable)Having a derivative, said of a function whose domain and codomain are manifolds.

   “A function which is differentiable wherever it is continuous is said to possess ordinary continuity.”

2. (comparable)able to be differentiated; distinguishable, as for example by differing appearance or measurable characteristics.

   “It would, in that case, have been as real as it now is, and would have been differentiable from its Maker as an effect is differentiable from its cause.”
