    Surely you know that \displaystyle \begin{align*} \csc{t} = \frac{1}{\sin{t}} \end{align*}...

    You are having trouble finding the relationship between 1 / sin(t) and sin(t)?

    It's very simple...

    \displaystyle \begin{align*} x &= \sin{t} \\ \\ y &= \csc{t} \\ &= \frac{1}{\sin{t}} \\ &= \frac{1}{x} \end{align*}
