In mathematics, a Carlyle circle is a certain circle in a coordinate plane associated with a quadratic equation; it is named after Thomas Carlyle. The circle has the property that the solutions of the quadratic equation are the horizontal coordinates of the intersections of the circle with the horizontal axis. Carlyle circles have been used to develop ruler-and-compass constructions of regular polygons.

Carlyle circle in the context of Thomas Carlyle
Thomas Carlyle (4 December 1795 – 5 February 1881) was a Scottish essayist, historian and philosopher. Known as the "sage of Chelsea", his writings strongly influenced the intellectual and artistic culture of the Victorian era.
Carlyle was born in Ecclefechan, a village in Dumfriesshire, Scotland. He attended the University of Edinburgh, where he excelled in mathematics and invented the Carlyle circle. After finishing the arts course he prepared to become a minister in the Burgher Church while working as a schoolmaster. He quit these and several other endeavours before settling on literature, writing for the Edinburgh Encyclopædia and working as a translator. He initially gained prominence in English-language literary circles for his extensive writing on German Romantic literature and philosophy. These themes were explored in his first major work, a semi-autobiographical philosophical novel entitled Sartor Resartus (1833–34).
