WebMay 23, 2024 · The set $\{(t−1)(t−2)/2, −t(t−2), t(t−1)/2\}$ is another basis for quadratic polynomials, called the Lagrange basis. I do not understand the concept of Lagrange basis functions, because they appear only when talking about a set of points and doing interpolation. So, I can define a Lagrange basis function only when I have a set of points. portchester health centre west streetWebThe Lagrange interpolation formula is a way to find a polynomial which takes on certain values at arbitrary points. Specifically, it gives a constructive proof of the theorem below. Suppose we have one point (1,3). How can we find a polynomial that could represent it?
