 If you enter a polar coordinate as in 1∠(π/4), and hit enter, and then hit the ∠ button again, it'll convert the number to it's rectangular/​complex form. If you enter a polar coordinate as in 1∠(π/4), and hit enter, and then hit the ∠ button again, it'll convert the number to it's rectangular/​complex form.

 +Note that if your system is set to radians by default, you can enter degrees by using shift-units and from the units menu, select angle-deg and the value will appear as 30_deg for example.
 +if you type 1∠30_deg and hit enter, it'll convert automatically to 1∠0.5325... (radians).
 +To enter a point this way in the geometry app, you cannot enter point(1∠30_deg),​ but you can enter 1∠30 on the home view and hit enter to convert to radians. Then, in the geometry app, you can enter point() and select menu-copy_from_home and select the radian version to put it in the point call. You can alternatively enter point(EXPR("​1∠30_deg"​)).
  
 The following function is a useful one to have in your arsenal. It will convert from polar to rectangular and vice versa...automatically. The following function is a useful one to have in your arsenal. It will convert from polar to rectangular and vice versa...automatically.
