What is the specific matrix representation of the derivative operator on the space of polynomials of degree at most 2 in the basis {1, x, x^2}?

Show answer

[[0, 1, 0], [0, 0, 2], [0, 0, 0]]

The derivative operator maps x^n to nx^(n-1), effectively shifting the basis vectors to a lower power. This results in a matrix with zeros on and below the diagonal, which is also nilpotent.

Also asked as:
  • In the basis {1, x, x^2}, what 3x3 matrix represents the derivative operator acting on polynomials of degree at most 2?
