Let T LPR denote the dierentiation operator on polynomials T
Let T L(P(R)) denote the dierentiation operator on polynomials:
T(p) := p\'
Prove or disprove: I, T, T^2 are linearly independent elements of L(P(R)).
Solution
they are linear independent elements.
consider polynomial
x^2
T(x^2) = 2x
T^2(x^2)= 2
all three are LI
