Hello,

I have read a lot on this group and other places but am still having a
hard time figuring this out. So here's a practical example that should
be easy to solve. Help will be very much appreciated!
How do I add these two phasors with the HP 50g?

(20 angle -30) + (40 angle 60) # phase is in degrees, angle denotes
that angle symbol

and I want to get:

44.72 angle 33.43
-or-
44.72 cos (wt + 33.43)

Thanks for the help!!

Directly. The angle symbol can be typed by ALPHA RS 6. Then when you
have both on the stack, press +

If it doesn't look like what you want, switch to SPHERE. You can
toggle quickly in the vector menu or by typing RECT or SPHERE

Thanks TW, that did the trick!

Perform DEG CYLIN (set modes) before proceeding:

Literal method:

(20\<)-30) (40\<)60) +

Alternate method (less typing, perhaps):

20 -30 \->V2 40 60 \->V2 +

\->V2 is found in MTH VECTR menu

A "custom menu" might facilitate either way:

{ DEG CYLIN "\<)" \->V2 } MENU

\->V2 produces complex numbers when flag -19 is set,
otherwise produces vectors (but with same components & result);
complex numbers may be easier to read in the display,
because they normally display on two lines if necessary.

May not work with real phasers:

Wow.

Thank you so much for that, it helps tremendously! Especially the
custom menu!
