< Strict inequality test. Returns 1 if the inequality is true, and 0

if the inequality is false. Note that more than two objects can

be compared. Thus 6 < 8 < 11 returns 1 (because it is true)

whereas 6 < 8 < 3 returns 0 (as it is false).

<= Inequality test. Returns 1 if the inequality is true, and 0 if the

inequality is false. Note that more than two objects can be

compared. See comment above regarding <.

<> Inequality test. Returns 1 if the inequality is true, and 0 if the

inequality is false.

= Equality symbol. Connects two members of an equation.

== Equality test. Returns 1 if the equality is true, and 0 if the

equality is false.

> Strict inequality test. Returns 1 if the inequality is true, and 0

if the inequality is false. Note that more than two objects can

be compared. See comment above regarding <.

>= Inequality test. Returns 1 if the inequality is true, and 0 if the

inequality is false. Note that more than two objects can be

compared. See comment above regarding <.

^ Inserts the power symbol.

a2q Returns the symbolic expression in quadratic form in the

variables given in VectVar of the symmetric matrix A.

a2q(MtrxA,VectVar)

Example:

a2q([[1,2],[4,4]],[x,y]) gives x^2+6*x*y+4*y^2

abcuv Returns the polynomials U and V such that for polynomials A,

B and C, PU+QV=R. With only polynomials as arguments, the

variable used is x. With a variable as the final argument, the

polynomials are expressions of it.

abcuv(Poly(A),Poly(B),Poly(C),[Var])

Example:

abcuv(x^2+2*x+1,x^2-1,x+1) gives [1/2,(-1)/2]

ACOS Arc cosine: cos

–1
