These prefixes allow for easily accessing a multiple of the 37 primary functions the

keyboard can take. You may keep the respective prefix pressed if you want to call

several functions in sequence showing the same label color. Any numeric entry will

just fill the display and is interpreted when completed, not earlier.

Time for a small example. Please take your WP 34S and press

 (i.e. the bottom left key) to turn your calculator on. You will get

Unless specified otherwise, we shall quote the numeric results only in the fol-

lowing, i.e.  here.

Now let us assume you want to fence a little patch of land 40 feet long and 30

feet wide. You have set the first corner post (A) already, and also the second

(B) in a distance of 30 feet from A. Where do you place the third post (C) to be

sure setting up the fence forming a proper rectangle? Simply enter:

 

  (this key is for separating two numbers in input here)

 

  ( is reached via and )

So, just take a 90 feet rope, nail its one end on post A and the other one on B,

fetch the loose loop and walk 40 feet away. As soon as both parts of the rope

are tightly stretched, stop and place post C there. You may set the fourth post

the same way.

This method works for arbitrary rectangles. Your WP 34S does the calculation

(or whatever lengths apply for you) automatically. You just care

for the land, the rope, hammer and nails. And it will be up to you to set the

posts!

As in this example, we will generally refer to shifted functions like  by just printing

the colored label in this text and omit the prefix key of corresponding color, since re-

dundant.

By the way, by pressing the function POL is called, converting rectangular to

polar coordinates. Most labels printed on your WP 34S simply call operations carry-

ing the same name as the respective label. There are, however, also a number of

cases like . Thus, let us introduce them, starting top left on the keyboard:

 , , , and  are called hotkeys, since they immediately call the user

programs carrying these labels if defined. If the respective labels are not (yet)

defined, these keys act as , , , or , respectively.
