Question
Let \( \mathbf{r}(t) = \langle \sin(6t), \cos(6t), \sin(6t) \cos(12t) \rangle \).

Find the point where \( \mathbf{r}(t) \) intersects the \( xy \)-plane on the interval \( \frac{2\pi}{23} < t < \frac{4\pi}{25} \).

(Use symbolic notation and fractions where needed. Give your answer as a point in the form \( (\ast, \ast, \ast) \).)
