信谊t
X (t) = 3 * t / (1 + t。^ 3);
Y (t) = 3 * (t ^ 2)。/ (1 + t。^ 3);
%刚刚Derivada
Dx = diff (X, t);
Dy = diff (Y, t);
D (t) =简化(Dy / Dx)。
%乙级联赛Derivada
Dx2 = diff (diff (X, t));
Dy2 = diff (diff (Y, t));
D2 (t) =简化(Dy2 / Dx)。
% Grafico做叶
-1.1 x = [linspace(-50年,10000年),linspace (-0.9, 10000);
散射(X (X), Y (X))
%的阴谋(Dy。/ Dx);
d = [linspace (5), linspace (-0.9)];
散射(Dx (d)、Dy (d))
