Loops back for polar display/input.
Checksum and length: 0548 90
Flags Used:
None.
Remarks:
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
Å
when done.
2. If your vector is in rectangular form, press
t
R and go to step 4. If your
vector is in polar form, press
t
P and continue with step 3.
