Movies of parametrized curves and tangents
Contents
A plane curve - a cusp
syms t
r = [t^3 t^2]
The file cusptan.mat was created with the commands
syms t r = [t^3 t^2] cusptan =curvetan(r,t,-1,1,-4,4,-3,3) save('cusptan','cusptan')
You can view the movie without executing those command by giving the commands:
load('cusptan')
mplay(cusptan)
A space curve - a helix
The file helixtan.mat was created with the commands
syms t helix = [cos(t), sin(t), t] helixtan =curvetan3(helix,t,0,6*pi,-1.5,1.5,-1.5,1.5,0,20,-38,30) save('helixtan','helixtan')
You can view it with the commands
load('helixtan')
mplay(helixtan)
