Find an equation of the tangent line to the curve $x = \sin\!\left(3t\right),\quad y=\sin\!\left(4t\right)$ at $t=\pi$.

$x(t) =$
$y(t) =$
(Note that because the correctness of a parametrically described line depends on both $x(t)$ and $y(t)$, both of your answers may be marked incorrect if there is an error in one of them.)
