4Polar
Displays vector in polar form [r q]. The vector
must be of dimension 2 and can be a row or a
column.

4Polar is a display-format instruction, not
a conversion function. You can use it only at the
end of an entry line, and it does not update
ans.

• Degree angle mode returns (rq).
• Radian angle mode returns r e

complexValue can have any complex form.
However, an r

i q
entry causes an error in Degree
angle mode.
Note:
You must use the parentheses for an (rq)
polar entry.
