Cheby1 (x) = x Cheby2 (x) = 2 * x * x - 1 Cheby3 (x) = 4 * x * x * x - 3 * x Cheby4 (x) = 2 * x * Cheby3(x) - Cheby2(x) Cheby5 (x) = 2 * x * Cheby4(x) - Cheby3(x) Cheby6 (x) = 2 * x * Cheby5(x) - Cheby4(x) Cheby7 (x) = 2 * x * Cheby6(x) - Cheby5(x) Cheby8 (x) = 2 * x * Cheby7(x) - Cheby6(x) Cheby9 (x) = 2 * x * Cheby8(x) - Cheby7(x) Cheby10 (x) = 2 * x * Cheby9(x) - Cheby8(x) Cheby11 (x) = 2 * x * Cheby10(x) - Cheby9(x) La fonction est tracé suivant : choose a function ChebyN choose x0, y0 choose h x = x0 y = y0 for i = 1 to max xold = x yold = y x = xold - h * ChebyN(yold) y = yold + h * ChebyN(xold) plot (x,y) next
