POLYNOMIAL

CAS: Display a menu or list of CAS operations with polynomials.

POP

Type: Command
Description: Restores the flags and current directory saved by the most recent execution of PUSH. If no
PUSH saves are left, the command has no effect.
...µ
Access:
Input:
None
Output: In Algebraic mode the command returns NOVAL to level 1 of the stack.

POS

Type: Command
Description: Position Command: Returns the position of a substring within a string or the position of an
object within a list.
If there is no match for obj or substring, POS returns zero.
!°L
Access:
!°
@& N

POTENTIAL

CAS: Find the potential field function describing a field whose vector gradient is input.

POWEXPAND

CAS: Rewrite an expression raised to a power as a product.

POWMOD

CAS: Raise number or expression to given power, expresse the result modulo the current modulus.
