This is not rocket science people, you are experienced tutors you can do this

Answer 1

`\begin{gathered} y=4csct \\ x=sint \\ y=4csct \\ y=(4)((1)/(sint)) \\ y=(4)((1)/(x)) \\ y=(4)/(x) \\ \end{gathered}`

Because t is in (0,pi)

`\begin{gathered} x1\text{ = }sin0 \\ x1=0 \\ \\ y1=(4)/(0)=\infty \\ \\ x2=sin\pi=sin180º=0 \\ y=(4)/(0)=\infty \\ \\ So\text{ if t\lparen0,}\pi),\text{ x is \lparen0,0}\rbrack \\ \\ Equation=\text{ }y=\text{ }(4)/(x)\text{ for }x(0,0\rbrack \end{gathered}`

That would be the rectangular equation
