Use the unit-circle diagram to find the terminal point for \(θ~=~\pi~/6\) and the exact values of \(\sin(θ)\), \(\cos(θ)\), and \(\tan(θ)\).

For a special angle, begin with its exact unit-circle point and the actual quadrant signs. Read cosine from the horizontal coordinate and sine from the vertical coordinate, then form tangent as sine over cosine. Keeping the radicals exact and rationalizing only at the end preserves the structure and makes sign checks easier.
