Second Order Lagrange Polynomial Example | Numerical Methods

In this video we are going to go through a second order Lagrange polynomial example so that you can see how we solve one of these problems. The Lagrange polynomial method is used to interpolate data between known discrete data points such that we can find the value of any input along our newly found continuous function.

This video is part of our Numerical Methods course. Numerical methods is about solving math problems through approximating the solution of problems that would be difficult or impossible to solve analytically. In this playlist we will cover topics such as solving systems of linear equations, solving systems of non-linear equations, numerical integration, numerical derivatives, etc..
