Given the data for the $4-$bar mechanism shown in the following figure:

$1\mathrm{.}1$ Using the Newton$-$Raphson Method determine the angles ${}_3$ and ${}_4$ in the Open Position.

From a rough sketch of the mechanism for the given input angle, estimate initial values for

angles ${}_3$ and ${}_4.$ Follow the example in your lecture notes and continue the iteration until

You may solve this problem by hand or with MatLab, $C++,$ Python, Excel,
