BUILT-IN MATHEMATICA SYMBOL
Roots
Roots[lhs==rhs, var]
yields a disjunction of equations which represent the roots of a polynomial equation.
- Roots uses Factor and Decompose in trying to find roots.
- You can find numerical values of the roots by applying N.
- Roots can take the following options:
-
| Cubics | True | whether to generate explicit solutions for cubics |
| EquatedTo | Null | expression to which the variable solved for should be equated |
| Modulus | 0 | integer modulus |
| Multiplicity | 1 | multiplicity in final list of solutions |
| Quartics | True | whether to generate explicit solutions for quartics |
| Using | True | subsidiary equations to be solved |
- Roots is generated when Solve and related functions cannot produce explicit solutions. Options are often given in such cases.
- Roots gives several identical equations when roots with multiplicity greater than one occur.
