Hace 3 días · The intermediate value theorem is used to verify the existence of an equation’s root in a given interval, which shows whether the given function has its zero (or f(x) = 0) within the interval (a, b). Let us verify this statement using the function f(x) = x 4 – 2x 3 + 3x – 21, which has a zero within the interval [1, 3] Step 1 ...

Hace 3 días · Given \(n>1\) and \(a_1, a_2, \ldots, a_n, b\) are non-zero integers, if \[\sum\limits_{i=1}^n{a_i^k}=b^k,\] then \(n\ge k\). Lander and Parkin found a counterexample with \(n=4\) and \(k=5\), which disproved this conjecture: \[27^5 + 84^5 + 110^5 + 133^5 = 144^5.\]
Hace 3 días · The proof makes use of the following lemma: If \alpha α is an algebraic number with degree n n, then there exists a real number A A such that \displaystyle \left|\alpha-\frac {p} {q}\right|>\frac {A} {q^n} ∣∣∣∣∣α− qp ∣∣∣∣∣ > qnA for all p p and q. q. Now, if L L is algebraic, then there exists some A A such that.
Since \( f(c)=0\), by the remainder theorem, we have \( f(x) = (x-c)h(x) + R = (x-c)h(x)\). Hence, \( x-c\) is a factor of \( f(x)\). Backward direction: If \( x-c\) is a factor of \( f(x)\), then (by definition) the remainder of \( f(x)\) upon division by \( x-c\) would be 0. By the remainder theorem, this is equal to \( f(c)\).
Hace 2 días · We propose a new notion of singularity in general relativity which complements the usual notions of geodesic incompleteness and curvature singularities. Concretely, we say that a spacetime has a volume singularity if there exist points whose future or past has arbitrarily small spacetime volume: in particular, smaller than a Planck volume. From a cosmological perspective, we show that the ...
Hace 3 días · The remainder = f (a) = 0. Thus, if (x – a) is a factor of f (x), then f (a) = 0. How to Use Factor Theorem. Let us find the factors of the polynomial f (x) = x 2 + 4x – 5. Assuming f (x) = 0 and solving further, we get. x 2 + 4x – 5 = 0. ⇒ x 2 + 5x – x – 5 = 0. ⇒ x (x + 5) – 1 (x + 5) = 0. ⇒ (x + 5) (x – 1) = 0.
