¶
ª
Divides previous result by the magnitude.
Calculates angle.
!
#$
Displays angle.
!
Loops back for polar display/input.
Checksum and length: 1DFC 040.5
Flags Used:
None.
Memory Required:
270 bytes: 182 for program, 88 for variables.
Remarks:
The length of routine S can be shortened by 6.5 bytes. The value –1 as shown
uses 9.5 bytes. If it appears as 1 followed by +/– , it will require only 3 bytes.
To do this, you can press 1

The terms "polar" and "rectangular," which refer to two–dimensional systems,
are used instead of the proper three–dimensional terms of "spherical" and
"Cartesian." This stretch of terminology allows the labels to be associated
with their function without confusing conflicts. For instance, if LBL C had been
associated with Cartesian coordinate input, it would not have been available
for cross product.
Program Instructions:
1. Key in the program routines; press
when done.
2. If your vector is in rectangular form, press
W
R and go to step 4. If your
vector is in polar form, press
W
P and continue with step 3.
