I need help with this question. I have been stuck at it for a few days. My main problem is how I use the curve $K_r$ to find the parametric representation.
I have a curve $K_r$ in the $(x,y)$-plane given by:
$r(u)= (sinh(u),cosh(u))$, u ∈ [0,2]
I have to find the parametric representation for the bounded region A that is bounded by $K_r$ and the line segments from (2,0) to r(0) and (2,0) to r(2).
