add
, SUBT
, MULT
: operations on polynomials
CHS
: opposite of a polynomial
POWER
: polynomial to a power. Ex:'X+2' 5 POWER -> 'X^5+10*X^4+40*X^3+80*X^2+80*X+32'
DIV2
: euclidean division, returns at stack level 2 the
quotient, and at stack level 1 the remainder
DIV1
: usual division
FDER
: derivative (with respect to VX
)
FINTG
: antiderivative (with respect to VX
). Works
for polynomial and rational fractions.
SQRT
: square root of a polynomial. Ex:'X^2+2*X+1' -> 'X+1'
DEGRE
(list polynomial only): order. Ex:{ 0 1 2 }
-> 1
L2S
: multiple variable polynomial evaluation. Ex:{ { 1 2 3} {4 5 6} } { X Y } L2S -> '(Y^2+2*Y+3)*X+(4*Y^2+5*Y+6)'
HORN
executes an Horner scheme. The syntax is:
verbatim20
This means that X2+2*X+3=(X+7)(X-5)+38.
PTAYL
: Taylor development (for polynomials only):2: P(X), 1: r -> P(X-r)
'X^3+2*X' 2 PTAYL -> 'X^3+6*X^2+14*X+12'
