Directions: Work in your group on the following problems. Each student turns in an individual worksheet

at the end of class, but you are expected to work as a team. The worksheet will be graded for participation

so do not worry if you don't finish all the problems.

$3-11.$ A one$-$link planar robot moves in the $x-y$ plane as shown in Fig. P$3\mathrm{.}11.$ For the given $l$ and $,$ find the position

$P(x,y)$ of the tip.
