How to find basis of a vector space.

I was attempting to find a basis of U = {p ∈P4(R): p′′(6) = 0} U = { p ∈ P 4 ( R): p ″ ( 6) = 0 }. I can find one by taking the most basic approach. Basically start with p(x) =a0 +a1x +a2x2 +a3x3 +a4x4 p ( x) = a 0 + a 1 x + a 2 x 2 + a 3 x 3 + a 4 x 4.Thus: f1(x1,x2,x3) = 1 2x1 − 1 2x2 f 1 ( x 1, x 2, x 3) = 1 2 x 1 − 1 2 x 2. Which, as desired, satisfies all the constraints. Just repeat this process for the other fi f i s and that will give you the dual basis! answered.
