Let V denote the vectore space of continuously differentiable functions, ƒ, over the interval [0,1] such that ƒ(0)=0.
Suppose Φ is-contained C∞ [0,1] (set of infinitely differentiable functions over the interval [0,1]) and define the operator
TΦ:V→R:ƒ→∫ƒ'(x)Φ(x)dx 0,1
Describe the null space of TΦ if Φ = x (Hint: integration by parts)
