    What's the definition of Chebyshev's polynomials ? I'd also hint that you can use the ODE which the polynomials solve exactly.


    P.S. The "p" in "Chepyshev" is actually reversed upside down and it's a "b".

    (1-x^2)y" - xy' + (n^2)y=0
    Am i have to solve this equation?

    i know how to write Chebyshev but it is just a mistake cause of fast typing.
