**dongo**, Wednesday, February 10, 2010 at 10:14amPretty easy. Use the fact that the product of the first derivatives of linear functions and their perpendiculars respectively are always -1.

This is:

Since we can choose an arbitrary function with the imposed properties, it suffices to take

g(x)=-2*x

q.e.d.
