Angle notation or phasor notation is a notation used in electronics. can represent either the vector or the complex number , with , both of which have magnitudes of 1. A vector whose polar coordinates are magnitude and angle is written  To convert between polar and rectangular forms, see Converting between polar and Cartesian coordinates.
In electronics and electrical engineering, there may also be an implied conversion from degrees to radians. For example would be assumed to be which is the vector or the number
