Root finding algorithm for f(a)f(b) > 0
Does anyone know of a root finding algorithm that doesn't rely on function values at given bounds being of opposite signs?
I am using the Brent algorithm, but this doesn't work for curves like a parabola re... | {"url":"http://mathhelpforum.com/advanced-math-topics/81701-root-finding-algorithm-f-f-b-0-a-print.html","timestamp":"2014-04-21T13:49:57Z","content_type":null,"content_length":"4617","record_id":"<urn:uuid:2a5ec180-a709-44a1-b147-2b3f1b2fa231>","cc-path":"CC-MAIN-2014-15/segments/1397609539776.45/warc/CC-MAIN-20140416... |
Event Horizon
Most commonly known as the point of no return, the event horizon is an astronomical point that has puzzled even Stephen Hawking, famous for his controversial theories towards black holes. It is a
sphere-like boundery surrounding the singularity of a black hole (Couper, H., & Henbest, N. 1996).

Modular inverse
From Algorithmist
The inverse of a number a modulo m is a number x such that $ax \equiv 1 \mod{m}$. It exists (and is unique if exists) if and only a and m are relatively prime (that is, gcd(a,m) = 1). In particular,
if m is a prime, every non-zero element of Z[m] has an inverse (thus making it an algeb... | {"url":"http://www.algorithmist.com/index.php/Modular_inverse","timestamp":"2014-04-19T17:01:14Z","content_type":null,"content_length":"21175","record_id":"<urn:uuid:aa7b8375-1739-4031-be9f-44928c97d912>","cc-path":"CC-MAIN-2014-15/segments/1398223205137.4/warc/CC-MAIN-20140423032005-00151-ip-10-147-4-33.ec2.internal.w... |

if $F = x^3yi +(y^2x -zx)j +(z^3 x^2 +y^2)k$ verify the identity
$abla \wedge (abla\wedge F) = abla(abla\cdot F) - abla^2 F$
my attempt
i found $abla\wedge(abla \wedge F)$ to be $(2y+6xz^2)i -(1+3x^2)j +(-2z^3-2)k$
