Need help with part b). Please Mathematica and show commands used. Thank you :)

 

1. Consider the polynomials
for k = 0,1, ...,11, and let B = {bo,b1,., b11}. It can be shown that B is a basis for P1, the vector space of polynomials of degree
at most 11. (You do not need to prove this.) Let pr(x) = xk for k = 0,1, ..., 11, so that S = {p0, P1,...,Pu} is the standard basis for
P11. Use Mathematica to:
