From Wikipedia, the free encyclopedia

Angle notation or phasor notation is a notation used in electronics.  \ang \theta can represent either the vector  (\cos \theta, \sin \theta)\,  or the complex number  \cos \theta + j \sin \theta = e^{j\theta},\,  both of which have magnitudes of 1.  A vector whose polar coordinates are  A  and  θ  is written  A \ang \theta.


In electronics, there may also be an implied conversion from degrees to radians. For example  \ang 90  would be assumed to be  \ang 90^\circ,  which is the vector  (0,1)\,  or the number  e^{j\pi/2}.\,
