Abstract
Dynamic visualizations of a sine graph and unit circle often use the same scaling for the vertical scale but the horizontal scaling in the sine graph often has a different scaling compared to the scaling of the circumference of the unit circle (i.e. for the radius and radians). I discuss some didactical implications for mathematics teachers.
