Happy New Year 2010! If the circumference of a circle located on the x-y plane is divided into equal arcs, the corresponding Cartesian points can be found from basic geometry and trigonometry. It is assumed that the circle has a radius of 5 and its origin is the point (6,3). The circumference is 2πr where r is the radius. The angle, Beta, between the y-axis and any point on the circumference is found from Beta = L/r where L is the arc`s length. The SINE and COSINE functions are used to determine the point x & y values. The calculation method in this animation was used to solve an engineering problem on magnetics using a finite elements method (FEM) software.Animated by Mustafa Daif for EduMaton.org
