1) Define a sequence of polynomials H n (x ) by H 0 (x )=1, H 1 (x )=2 x , and for n>1 by H n+1 (x )=2 x H n (x )−2 n H n−1 (x ) . These polynomials are called Hermite polynomials of degree n. Calculate the first 7 Hermite polynomials of degree less than 7. You can check your results by comparing them to the list of Hermite polynomials on wikipedia (physicist's Hermite polynomials). 2)...

Take a tour of the Internet and locate a MRP system that has not already been shared with the class. Tell us how this system can help alleviate one of the inventory problems identified in the chapter this week. Does your MRP system help with JIT as well? If so how? What kinds of calculations are needed in MRP and JIT?
