Functions and commands 197

OR Logical Or. Returns 1 if either or both sides evaluates to true

and 0 otherwise.

Expr1 OR Expr2

Example:

3 +1==4 OR 8 < 5 returns 1

order_size Returns the remainder (O term) of a series expansion:

limit(x^a*order_size(x),x=0)=0 if a>0.

order_size(Expr)

pa2b2 Takes a prime integer n congruent to 1 modulo 4 and returns

[a,b] such that a^2+b^2=n.

pa2b2(Integer)

Example:

pa2b2(17) gives [4 1]

pade Returns the Pade approximation of an expression, i.e. a

rational fraction P/Q such that P/Q=Expr mod x^(n+1) or

mod N with degree(P)<p.

pade(Expr, Var, Integern, Integerp)

Example:

pade(exp(x), x, 5, 3) returns

PI Inserts π.

PIECEWISE Used to define a piecewise-defined function. Takes as

arguments pairs consisting of a condition and an expression.

Each of these pairs defines a sub-function of the piecewise

function and the domain over which it is active.
