drawing a function in sketcher mode

(OP)
hi all,

I want to draw a part which is mainly an extruded section.
the problem is that the sketch of the section is complicated and given by an equation y=f(x) ( a polar one also). how can i draw a function in the sketcher mode?
i know that i can plot a number of points satisfying the equation using relations, and then interpolate the points with splines. Is there any other easier way?

To extend John's answer a bit, create the curve outside of sketcher, as he suggested, then start the sketch and copy the curve using the Use Edge tool.
