More generally, if an equation P(x) = 0 of prime degree p with rational coefficients is solvable in radicals, then one can define an auxiliary equation Q(y) = 0 of degree p – 1, also with rational coefficients, such that each root of P is the sum of p-th roots of the roots of Q.
In 1824, the Abel–Ruffini theorem established that polynomial equations of a degree of five or higher could have no solutions in radicals.It became clear to mathematicians since then that one needed to go beyond radicals in order to express the solutions to equations of the fifth and higher degrees.
For polynomials in two or more variables, the degree of a term is the sum of the exponents of the variables in the term; the degree (sometimes called the total degree) of the polynomial is again the maximum of the degrees of all terms in the polynomial. For example, the polynomial x 2 y 2 + 3x 3 + 4y has degree 4, the same degree as the term x ...
Except for n equal to 1 or 2, they are palindromes of even degree. The degree of Φ n {\displaystyle \Phi _{n}} , or in other words the number of n th primitive roots of unity, is φ ( n ) {\displaystyle \varphi (n)} , where φ {\displaystyle \varphi } is Euler's totient function .
The suspect in the New Orleans attack that killed 14 people on New Year's Day is believed to have acted alone in a "premeditated and evil act," the FBI has said. The latest information is counter ...
Petri's theorem, often cited under this name and published in 1923 by Karl Petri (1881–1955), states that for g at least 4 the homogeneous ideal defining the canonical curve is generated by its elements of degree 2, except for the cases of (a) trigonal curves and (b) non-singular plane quintics when g = 6. In the exceptional cases, the ideal ...
