Given that the anti-differentiation $T : \mathbb{R}[x] \to \mathbb{R}[x] $ is a linear operator. Find the coefficient polynomials $Q_k(x)$ of $T$ in the representation $T = \sum_{k=0}^{\infty} Q_k(x)D^k$.
I figure I may have to use induction but not sure how to put it together Let $Q_0(x)=T[1]$ repeat for $Q_1(x), \cdots, Q_{n-1}(x)$ then set
$Q_n(x)= \frac{1}{n!}\left(T[x^n]- \sum\limits_{k=1}^{n-1}Q_k(x)D^k[x^n] \right)$
Now then somehow show that this will agree with $T$ on every polynomial $p \in \mathbb{R}[x]$
