Mathematical Tutorial of the PeaucellierLipkin Linkage
by David W. Henderson & Daina Taimina 



We study the mathematics behind the PeaucellierLipkin linkage in three problems: Problem 1. Circles in the Plane, which explores some geometry of circles. Problem 2. Inversions in Circles, which explores properties of inversion in circles. Problem 3. Applications of Inversions to the PeaucellierLipkin Linkage, which explores the applications of Problems 1 and 2 to an understanding of the linkage. intended audiences : Undergraduate upper division, Graduate or professional, General public Models :
