EXERCISE 2-1

a = 1; b = 1/(2*pi); % radius and pitch of helix. d = sqrt(a^2 + b^2); % common term for components. S = linspace(0,4*pi,100); % vector of natural parameter values. X = a*cos(S/d); % x-component of vector function for curve. Y = a*sin(S/d); % y-component. Z = (b/d)*S; % z-component. plot3(X,Y,Z,'k') % plot the helix. axis equal, grid on, box on ... ................
