Coefficients Command

Coefficients( <Polynomial> )

Yields the list of all coefficients ak,ak1,,a1,a0 of the polynomial akxk+ak1xk1++a1x+a0.

Coefficients(x^3 - 3 x^2 + 3 x) yields {1, -3, 3, 0}.

For non-polynomial curves obtained using one the fitting commands e.g. f(x) = FitExp(l1), the command Coefficients(f) will return the list of the calculated parameters.

Coefficients( <Conic> )

Returns the list of the coefficients a, b, c, d, e, f of a conic in standard form: ax2+by2+c+dxy+ex+fy=0

For a line in implicit form l: ax + by + c = 0 it is possible to obtain the coefficients using the syntax x(l), y(l), z(l).

Given line l: 3x + 2y - 2 = 0:

  • x(l) returns 3

  • y(l) returns 2

  • z(l) returns -2

CAS Syntax

Coefficients( <Polynomial> )

Yields the list of all coefficients of the polynomial in the main variable.

Coefficients(x^3 - 3 x^2 + 3 x) yields {1, -3, 3, 0}.

Coefficients( <Polynomial>, <Variable> )

Yields the list of all coefficients of the polynomial in the given variable.

  • Coefficients(a^3 - 3 a^2 + 3 a, a) yields {1, -3, 3, 0}.

  • Coefficients(a^3 - 3 a^2 + 3 a, x) yields {a³ - 3 a² + 3 a}.
