- Coefficients[ <Polynomial> ]
- Yields the list of all coefficients of the polynomial.
- Example:
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[ <Conic> ]
- For conics in standard form a\cdot x^2 + b\cdot y^2 + c + d\cdot x\cdot y + e\cdot x + f\cdot y = 0 returns list \{a, b, c, d, e, f\}.
CAS Syntax
- Coefficients[ <Polynomial> ]
- Yields the list of all coefficients of the polynomial in the main variable.
- Example:
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.
- Example:
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 a, andCoefficients[a^3 - 3 a^2 + 3 a, x]
yields \{a^3 - 3 a^2 + 3 a\}.
