[Tex/LaTex] Drawing angles greater than 360º inTikZ


When teaching trigonometry, sometimes it is useful to represent angles greater than 360º with some kind of "spiral arc". For example:


the angle of -440º in the figure.

My question is:

How can I do this in nicely TikZ?

I can do it by using several consecutive arcs, but I wish to know if is there a more elegant solution to this.

      plot ({(\t+#2)*cos(\t)/(#2)},
           {(\t+#2)*sin(\t)/(#2)}) node[right=.5cm] {$#2^\circ$}

 \draw [thick] ( 0,0) -- (3,0);
 \draw [thick] ( 0,0) -- (0,3); 
 \draw [red,thick] ( 0,0) -- (400:3);
