Homework Statement



Eliminate the parameter to find a Cartesian equation for the curve.
X=sin(t), y=csc(x)

Homework Equations





The Attempt at a Solution


Is this correct?
X=sin(t)
Arcsin(x)=t
So y=csc(arcsin(x)

Can I simplify it further?

is the second equation a typo: x=sin(t), y=csc(x) should it be y=csc(t)?

from your substitution it appears that is what you think it is.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
