How to Eliminate the Parameter????

x=sint y=csct 0<t<pi/2

so eliminate the parameter to find the cartesian equation....

Please help!!

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)?

the answer is suppose to be y=1/x , y>1 but how do i show my work for that?

It's very simple...

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