Polynomial Command
From GeoGebra Manual
- Polynomial( <Function> )
- Yields the expanded polynomial function.
- Example:
Polynomial((x - 3)^2)
yields x2 - 6x + 9.
- Example:
Polynomial(f(x,y)=y^2+(x+y)^2)
yields x2+2xy+2x2.
- Polynomial( <List of Points> )
- Creates the interpolation polynomial of degree n-1 through the given n points.
- Example:
Polynomial({(1, 1), (2, 3), (3, 6)})
yields 0.5 x2 + 0.5 x.
CAS Syntax
- Polynomial( <Function> )
- Expands the function and writes it as a polynomial in x (grouping the coefficients).
- Example:
Polynomial((x - 3)^2 + (a + x)^2)
yields 2 x2 + (2a - 6) x + a2 + 9.
- Polynomial( <Function>, <Variable> )
- Expands the function and writes it as a polynomial in the variable (grouping the coefficients).
- Example:
Polynomial((x - 3)^2 + (a + x)^2, a)
yields a2 + 2 x a + 2 x2 - 6 x + 9.
