Show that the Chebyshev polynomial T3(x) is a solution of Chebyshev's equation of order 3. 3. By means of the recurrence formula obtain Chebyshev polynomials T2 ...

Chebyshev Polynomials Previously we have learned how to compute minimax polynomials for certain special cases, but in general this is quite di cult. One minimax problem that can be solved is the problem of computing the minimax polynomial of a function f(x) that is itself a polynomial, where the approximation must have lower degree.
