oh!! that would be crystal clear. Are the midpoints of chords subtending 2pi/3 at center?

dw:1357461957504:dw so that'd be half of it,ofcorse.. you can relate this from the fact that both right triangles are congruent..

@@experimentX you misunderstood. it says the locus of mid points of all those chords, which subtend angle 2pi/3 at center the chord subtends angle 2pi/3 at the center..

your equation will be a circle with center at 0,0 ... just find the radius using trigonometry.

As @experimentX said use trigonometry to find OM
