Hello all, I do not know how to write ( 3 , i * ( 3 * sqr( 3 ) ) ) in RPN mode.
Can anyone please help me? I have already searched the gug pdf guide for help to no avail.

A few notes when representing a complex number as a vector:
1) the i is omitted, the second number is assumed to be the imaginary part.
2) the 50g only accepts decimals for vector representation
So, to input it. I assume you have the calculator in Complex mode and Exact mode (Approx not ticked in "MODE" -> "CAS"), i.e. "C=" displayed on top of the screen.
In RPN mode:
Press 3 then ENTER (3 is on level 1 )
Press ENTER again (3 is now duplicated and on both level 1 and 2 - an advantage of RPN)
Press ENTER again (3 is now duplicated and on levels 1, 2 and 3)
Press the SQRT(X) button. Level 1 shows a 3 with a square root sign.
Press multiply key, level 1 shows 3·SQRT(3)
Press LeftShift (white) then i (above TOOL key), level 1 shows an i
Press multiply key, level 1 shows 3·SQRT(3)·i
Press + key, level 1 shows 3+3·SQRT(3)·i (or 3·SQRT(3)·i+3 depending on Flag -27 setting)
If you wish to keep the symbolic result (with "SQRT" symbol), leave it in this form, if you wish to convert it to vector form press RightShift (red) then ->NUM (above ENTER key).
The result will be a decimal vector form, (3.,5.19615242271).
