- Factors( <Polynomial> )
- Gives a list of lists of the type {factor, exponent} such that the product of all these factors raised to the power of the corresponding exponents equals the given polynomial. The factors are sorted by degree in ascending order.
- 예:
Factors(x^8 - 1)yields {{x - 1, 1}, {x + 1, 1}, {x^2 + 1, 1}, {x^4 + 1, 1}}. - 노트: Not all of the factors are irreducible over the reals.
- Factors( <Number> )
- Gives matrix of the type \left( \begin{array}{} prime_1 & exponent_1 \\ prime_2 & exponent_2 \\prime_3 & exponent_3 \\ \end{array} \right) such that the product of all these primes raised to the power of the corresponding exponents equals the given number. The primes are sorted in ascending order.
- 예:
Factors(1024)yields ( 2 10 ), since 1024 = 2^{10}.Factors(42)yields \left( \begin{array}{} 2 & 1 \\ 3 & 1 \\7 & 1 \\ \end{array} \right) , since 42 = 2^1・3^1・7^1.
