☆☆why circle is the most fundamental figure ?
Answers
The circle apears very often in problems that involves periodicity, since sines and cossines are related to a circle. Circles also define a fixed distance function that may be used in many definitions fundamental to multivarable calculus (bounded regions, compact regions, region boudary and other...). Ofcourse there are many other uses.
