PositiveDefiniteMatrixQ (Built-in Mathematica Symbol)

PositiveDefiniteMatrixQ[m] tests whether m is a positive definite matrix.

Positive (Built-in Mathematica Symbol)

Positive[x] gives True if x is a positive number.

PossibleZeroQ (Built-in Mathematica Symbol)

PossibleZeroQ[expr] gives True if basic symbolic and numerical methods suggest that expr has value zero, and gives False otherwise.

Postfix (Built-in Mathematica Symbol)

Postfix[f[expr]] prints with f[expr] given in default postfix form: expr // f. Postfix[f[expr], h] prints as exprh.

PowerDistribution (Built-in Mathematica Symbol)

PowerDistribution[k, a] represents a power distribution with domain parameter k and shape parameter a.

PowerExpand (Built-in Mathematica Symbol)

PowerExpand[expr] expands all powers of products and powers. PowerExpand[expr, {x_1, x_2, ...}] expands only with respect to the variables x_i.

PowerModList (Built-in Mathematica Symbol)

PowerModList[a, s/r, m] gives a list of all x modulo m for which x^r \[Congruent] a^s mod m.

PowerMod (Built-in Mathematica Symbol)

PowerMod[a, b, m] gives a^b mod m. PowerMod[a, -1, m] finds the modular inverse of a modulo m.PowerMod[a, 1/r, m] finds a modular r\[Null]^th root of a.

Power (Built-in Mathematica Symbol)

x^y gives x to the power y.

PowersRepresentations (Built-in Mathematica Symbol)

PowersRepresentations[n, k, p] gives the distinct representations of the integer n as a sum of k non-negative p\[Null]^th integer powers.
