What about MTH>VECTR> ->V2 ?

You can also type polar vectors directly into the command line, in either parentheses or square brackets:

(2 ∡3)
[2 ∡3]

The angle symbol is obtained by pressing ALPHA left-shift 6. When you press ENTER, the angle will be interpreted according to the current DEG/RAD/GRAD setting, and the vector will be displayed according to the current RECT/CYLIN/SPHERE setting. 3D vectors of course can only be typed in square brackets, not parentheses:

[1 ∡2 ∡3] or [1 ∡2 3]
