\textbf{To find:}

\textsf{The terminal point for a $60^\circ$ angle in a unit circle}

\textbf{Solution:}

\underline{\mathsf{Concept\;used:}}

\mathsf{Any\;point\;on\;the\;circle\;of\;radius\;r\;is\;(r\,cos\theta,\;r\,sin\theta)}

\textsf{Here, the radius of the circle r=1}

\mathsf{and\;\theta=60^\circ}

\mathsf{The\;co-ordinates\;of\;the\;terminal\;point\;are}

\mathsf{(r\,cos\theta,\;r\,sin\theta)}

\mathsf{(1(cos60^\circ),\;1(sin60^\circ))}

\mathsf{(cos60^\circ,\;sin60^\circ)}

\implies\boxed{\mathsf{\left(\dfrac{1}{2},\;\dfrac{\sqrt3}{2}\right)}}

\textbf{Answer:}

\mathsf{option\;(A)\;is\;correct}
