    Is there anybody here can give me a chemical engineering example that the final differential equation will be LAGUERRE ?

    I've tried finding an example that wasn't buried in a journal. Still working on it.

    Laguerre functions/polynomials are obviously the solutions of the Laguerre differential equation:

    x y'' + (1-x) y' + [itex]\lambda[/itex] y = 0.

    Laguerre functions show up in process control - http://www.chemengr.ucsb.edu/~ceweb/faculty/seborg/pdfs/Book_review_Cluett_pub.pdf
