uniform_icdf

The inverse cumulative uniform probability density function. Returns the value x such that the uniform lower-

tail probability of x, given parameters a and b, is p.

uniform_icdf(a, b, p)

Example:

uniform_icdf(3.2, 5.7, 0.48) returns 4.4

UNION

Concatenates the inputs in a list where all duplicates have been removed.

Example:

UNION({1,2,3}, {2,4,8}, 10) returns {1, 2, 3, 4, 8, 10}

valuation

Returns the valuation (degree of the term of lowest degree) of a polynomial. With only a polynomial as

argument, the valuation returned is for x. With a variable as second argument, the valuation is performed for

it.

valuation(Poly,[Var])

Example:

valuation(x^4+x^3) gives 3

variance

Returns the variance of a list or the list of variances of the columns of a matrix. The optional second list is a

list of weights.

variance(List1, [List2]) or variance(Matrix)

Example:

variance({3, 4, 2}) returns 2/3

vpotential

Given a vector V and a vector of variables, returns the vector U such that curl(U)=V.

vpotential(Vector1, Vector2)

Example:

vpotential([2*x*y+3,x2-4*z,-2*y*z],[x,y,z]) returns

VERSION

Returns a string containing the version numbers of the various components of the system, as displayed in the

“About HP Prime calculator” help page. Given an integer n, returns only the version number for that specic

component. The components are identied by the following integers:
