- Coefficients( <Polynomial> )
- Yields the list of all coefficients a_k,a_{k-1},\ldots,a_1, a_0 of the polynomial a_kx^k+a_{k-1}x^{k-1}+\cdots+a_1x+a_0.
- 예:
Coefficients(x^3 - 3 x^2 + 3 x)yields {1, -3, 3, 0}, the list of all coefficients of x^3 - 3 x^2 + 3 x. - 노트: There's a special mode (for non-polynomials) for the output of the fitting commands eg if
f(x) = FitExp(l1)thenCoefficients(f)will return the calculated parameters - Coefficients( <Conic> )
- Returns the list of the coefficients a, b, c, d, e, f of a conic in standard form: a\cdot x^2 + b\cdot y^2 + c + d\cdot x\cdot y + e\cdot x + f\cdot y = 0
- 노트: 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).
- 예: Given
line: 3x + 2y - 2 = 0:x(line)returns 3y(line)returns 2z(line)returns -2

- Coefficients( <Polynomial> )
- Yields the list of all coefficients of the polynomial in the main variable.
- 예:
Coefficients(x^3 - 3 x^2 + 3 x)yields {1, -3, 3, 0}, the list of all coefficients of x^3 - 3 x^2 + 3 x. - Coefficients( <Polynomial>, <Variable> )
- Yields the list of all coefficients of the polynomial in the given variable.
- 예:
Coefficients(a^3 - 3 a^2 + 3 a, a)yields {1, -3, 3, 0}, the list of all coefficients of a^3 - 3 a^2 + 3 aCoefficients(a^3 - 3 a^2 + 3 a, x)yields {a³ - 3 a² + 3 a}.
