Hello the question is written in the beginnig and i don't know how to do the graph, plus i have an hesitation about the way to find t. Our teach said that it was an obligation to do it using determinants of a matrice. I also have have doubts about the second derivative

I can't see your x(t) and y(t) clearly. Is this the question?
[math]x(t)=\frac{t}{t^2-1}[/math][math]y(t)=\frac{t^2}{t-1}[/math]
 
Nvm, I couldn't read your t and 1. It's fine. My appologies.

I.e the graph

To graph, first, look at your functions and determine the holes, asymptotes. Second, find your critical values i.e. the max/min using the first derivative.
Third, use the second derivative test to determine concavity.
Do one function at a time. Start with x(t). Can you find all of those things?
