- Root[ <Polynomial> ]
- Yields all roots of the polynomial as intersection points of the function graph and the x‐axis.
- Root[ <Function>, <Number a> ]
- Yields one root of the function using the initial value a for Newton's method.
- Root[ <Function>, <Number a>, <Number b> ]
- Yields one root of the function in the interval [a, b] (regula falsi).
CAS Syntax
- Root[ <Polynomial> ]
- Yields all roots of the polynomial as intersection points of the function graph and the x‐axis.
- Example:
Root[x^3 - 3 * x^2 - 4 * x + 12]yields {x = 3, x = 2, x = -2}.
Note:
This command is only a special variant of Solve Command.
