Notes on Linear Algebra for Polynomials
We’ll be working with the set P_n(\mathbb{R}), real polynomials
of degree \leq n. Such polynomials can be expressed using
n+1 scalar coefficients a_i as follows:
\[p(x)=a_0+a_1 x + a_2 x^2 + \cdots + a_n x^n\]
Vector space
The set P_n(\mathbb{R}), along with …...
