- ComplexRoot[<Polynomial>]
- Finds the complex roots of a given polynomial in x. Points are created in Graphics View.
CAS Syntax
- ComplexRoot[<Polynomial>]
- Finds the complex roots of a given polynomial in x.
- Example:
ComplexRoot[x^2 + 1]gives {x = ί, x = -ί}, the complex roots of x2 + 1.
Note:
- The complex ί is obtained by pressing ALT + i. See also Complex Command.
- See also CSolve Command.
