# Question: the set of all differentiable functions defined on the interval...

###### Question details
The set of all differentiable functions defined on the interval [a,b] such that if f is in the set, then f(a) =f(b) =0. Notice that each succeeding set of functions is a subset of the proceding sets, but is still a linear space
