Chapter 1.1, Problem 61E

For the following exercises, use a graphing utility to graph the curve represented by the parametric equations and identify the curve from its equation.

61. $\left[T\right]$ Sketch the curve given by parametric equations

   $\begin{array}{l}x=\cosh \left(t\right)\\ y=\sinh \left(t\right)\end{array}$ where $-2\le t\le 2$ .
