circular measure การใช้

The one dimensional circular measure has the units of radians or degrees, while the two dimensional one is expressed in steradians.
C-3D . Weight for fishing nets, one has circular measure 3.3 cm diameter and 5 cm wide and oval shaped fragment.
An alternative symbol is c, the superscript letter c, for " circular measure ", or the letter r, but both of those symbols are infrequently used as it can be easily mistaken for a degree symbol ( ?) or a radius ( r ).
The laws of rational trigonometry, being algebraic and'exact-valued', introduce subtleties into the solutions of problems, such as the non-additivity of quadrances of collinear points ( in the case of the triple quad formula ) or the spreads of concurrent lines ( in the case of the triple spread formula ) absent from the classical subject, where linearity is incorporated into distance and circular measure of angles, albeit'transcendental'techniques, necessitating approximation in results.
