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  $e^{j\pi/2}.\,$
