# Tikz: using functions for calculaton x, y parts of the coordinate in the stream of path operations

Is it possible to write something like this?

\draw[dotted] (pi*0.5,sin(pi*0.5)) -- ++(10,0);

I would like to use the trigonometric functions when entering x, y-parts of the coordinates. I got Package Tikz error. It is incorrect syntax, or this method is not possible?
