Of course you would! It would be easy using what we have learned.

In the difficult problems section you are asked to find that the Peaucellier linkage (or Peaucellier-Lipkin linkage) computes the function


Assuming this as fact, can the function w=z^2 be found, as a linkage?

This is difficult, you probably won't get the right expression, but you try a few things before going on.
