Lagrange polynomial

Lagrange polynomials are a type of math that helps you figure out what to do when you have a bunch of points on a graph and you want to draw a line that goes through all of them. It's like a game of connect-the-dots. To do this, you use Lagrange polynomials, which are equations that "connect the dots" for you. So if you have a bunch of dots (points) on a graph, Lagrange polynomials can help you draw the curvy line that goes through all your points - like connect-the-dots!
