SUMMARY

The discussion focuses on the mathematical representation of the operator T defined as T = D + D ∘ D in the context of polynomial vector spaces. Here, D represents a differential operator acting on the vector space V of polynomials with real coefficients of degree less than or equal to 3. The composition operator D ∘ D signifies applying the differential operator D twice, which is crucial for understanding the behavior of T when applied to the basis b = {1, t, t², t³} of V.

what this circle mean??

v is vectoric space of all polinomials <=3 with coefficient of R
D:v->v
T:v->v
i need to find the operator of
[tex] T=D+D\circ D[/tex]

find T regarding b={1,t,t^2,t^3} of V

It usually means composition. For example, [itex](f \circ g)(x)[/itex] is f(g(x)).
