One of the super-powers of linear algebra is that it can be applied everywhere. In the next question, you will use linear algebra to solve a non-linear problem. Given a list of n points (x,y) R with distinct a, values, it is sometimes necessary to find a polynomial curve p(x) Pn 1(R) passing through all the points. One method to do so, uses linear algebra as follows. (We will learn another method, called Lagrange interpolation, later in the course.) Consider an arbitrary polynomial p(x) = ao + a₁x + a₂x²+...+ an-1" We consider the coefficients as unknown. Each point (U) gives a linear relation among the coefficients. The linear system is given: ao + a₁x₁ + a₂x² + ... + an_1x₁ ao + a₁x2 + a₂x² + n-1 + an 1x2 1 ao+an + ax² + + an 1 xn = Yı Y2 Yn 1.
