solving as matlab code ok when Icode

close all; clear; clc;

syms t f = t^2; g = (5*t) - 1; h = 2*t^3 - t; r = [f, g, h]; % r(t)

dr = diff(r, t); % r'(t) = tangent to the curve T = dr / norm(dr); % normalized r'(t) = T(t) = unit tangent to the curve dT = diff(T, t); % T'(t)

k = norm(dT)orm(dr); % Curvature at a given t ( k = ||T'(t)|| / ||r'(t)|| ) k = subs(k, 1); % Curvature at t = 1 disp('Curvature at t = 1:'), disp(k) disp('Or, approximately:'), disp(double(k))

ok when i put these code i still find two mistakes
