3.2.2.1 Lagrange interpolation The principles of Lagrange interpolation were introduced in the lecture. Recall that this takes a set of n +1 data points, (æk, fk) with k = 0,..., n, and defines Lagrange basis polynomials by Lk(x) = n II 20 i=0 i#k T-Ti Thi k = 0,..., n. The Lagrange interpolating polynomial is then defined by n P(x) = Σ fkLk (x). k=0 (3.1) (3.2) Note that, for convenience in Python, indices in equations (3.1) and (3.2) start at 0. There are n+ 1 interpolation points and P(x) is therefore of degree n. CHAPTER 3. INTERPOLATION 1. Write a function lagrange_poly which computes the kth Lagrange basis polynomial. It should take as arguments an array of points x, the list of interpolation points xk, and an integer k, and return an array of numbers L(x) according to (3.1). 2. Write a function interpolating_poly which computes the Lagrange interpolating polynomial given by (3.2). It should take as arguments an array of points x and lists of data points k and fk, and call the…

1- Write a C program for Arduino that controls a set of two traffic lights A & B at a crossroads. Assume that: • When the traffic lights (A) are green or amber, the traffic lights (B) are red. • When the traffic lights (B) are green or amber, the traffic lights (A) are red. Green lights must stay on for 15 seconds, amber lights for 5 seconds and red lights for 20 seconds. 2- Sketch the circuit diagram to wire the Arduino to the two traffic lights.
