Existence of Topologically Transitive Maps on nice Metric Spaces

Let $(X,d)$ be a separable metric space with no isolated points. Recall that a continuous function $T:(X,d)\rightarrow (X,d)$ is called topologically transitive if Given $U,V$ non-empty open subsets ...

Is the sequence $(a_n)$ defined by $a_n=\tan{a_{n-1}}$, $a_0=1$, dense in $\Bbb{R}$?

Let $a_0=1,a_n=\tan{a_{n-1}}$. Then is $\{a_n\}_{n=0}^\infty$ dense in $\Bbb{R}$? I've drawn a map of this dynamical system and it seems that the sequence is dense on $\Bbb{R}$.
