WebThe Chebyschev polynomial of degree n on [− 1, 1] is defined by T n (x) = cos(nθ), where x = cos θ with θ ∈ [0, π]. This is a polynomial since we can expand cos(nθ) as a degree n polynomial of cos θ, by Moivre formula. The most important feature of Chebyshev polynomial T n is that the critical values are obtained at n + 1 WebWe use Chebyshev polynomials to approximate the source function and the particular solution of an ordinary di erential equation. The derivatives of each Chebyshev polyno-mial will be represented by linear combinations of Chebyshev polynomials, and hence the derivatives will be reduced and di erential equations will become al-gebraic equations. greenhouse gas emission large facilities
