The Euclidean Rotation Group and Complex Number Multiplication - WildTrig

Explore the connection between the Euclidean rotation group and complex number multiplication in this 21-minute mathematics video. Delve into a rational formulation of rotations, moving away from the traditional angular description using cosine and sine values. Discover how this approach relates to complex number multiplication in the plane and introduces the concept of half-slope on the unit circle. Learn about the crucial importance of rotations in understanding two-dimensional dynamics and graphics, and gain insights into a new perspective on this fundamental mathematical concept.
