How can I use a variable in Quiver?

I want to use a variable in Quiver.

like this

if true
t = linspace(0,4*pi,1000);
quiver(0,0,sin(t),cos(t))
   end

The final result that I want is an animation a line following the point in quiver.

Thank you!

The above quiver command doesn't seem to be valid as the dimension of the first argument must be equal to that of the third and that of the second argument must be equal to that of the fourth.

Anyway, in order to make an animation, you may use a combination of 'for' loop, 'pause' and 'drawnow' functions. Have a look into the documentation for 'drawnow' here:
