8. The curve \(C\) has polar equation
$$r = \sin 2 \theta , \quad \text { where } \quad 0 < \theta \leqslant \frac { \pi } { 2 }$$
- Find the polar coordinates of the point on \(C\) at which the tangent is parallel to the initial line. Give your answers correct to three decimal places.
- Write the coordinates of this point in Cartesian form.
