50g Phasors

#Tips for calculating phasor quantities using the 50g:

## Adding ->V2, RECT and CYLIN to soft menu

* We often need to convert between rectangular and polar form. Lets add these commands to the CUSTOM softmenu.
* V2 builds a two-dimensional vector using the first two stack values and builds in polar/rectangular depending on mode.
* RECT and CYLIN don't convert the first stack value as I thought they did, but instead set the coordinate mode.

* [white] [mode=>custom] # to open custom softmenu
* {->V2 RECT CYLIN} [enter] MENU [enter] # caps values can be fetched from the [CAT]alog

## Entering complex values

* Make sure complex mode is on
* For rectangular values, enter between round parenthesis with a space. ie 5+j3 would be (5 3)
* For polar values, enter between round parenthesis spaced with angle symbol ([alpha][red][6]). ie 5 at 30 degrees would be (5<30)

## Entering complex values, better

* As described above, setup a custom softmenu with the ->V2, RECT and CYLIN/POLAR functions.
* For rectangular values, switch to rectangular coordinate system, put your two components on the stack, and ->V2
* For polar values, switch to polar system, put r and angle on the stack, then ->V2
* To switch your answer between the two, you can just switch coordinate systems. All complex values are stored in rectangular form and displayed according to the chosen system.
