    If you start with a ray pointing along the x-axis \theta = 0, if you rotate the ray \theta = \frac{\pi}{3}, then move aong the ray 4 unit (this is v), this determines a point. From this, you can draw a triangle in the first quadrant. The vector you seek is

    <|\,v\,|\, \cos \theta,\; |\,v\,| \sin \theta >
