Trigonometric form of a number
Okay, I don't know how to find just theta either on my calculator or just by hand.
The problem was 5+2i.
I get the square root of 29.
I get 2/5.
I have to turn tan(2/5) into approximately 0.38.

In this thesis, experiments with magnetic liquids and gels are presented. Ferrofluids are synthetically created suspensions of magnetic nanoparticles in a carrier liquid. By adding a gelator,
such a ferrofluid can be turned into a ferrogel.

$15A^2B^3+10A^2B^2+5AB^3$ In each bit you can divide by 5 without leaving any remainder. You can also see there's an $A$ in each bit. Also, there's a $B$ in each bit. In fact, there's at least 2
$B$'s in each bit. So you can extract a 5, an $A$ and two $B$'s. This gives, for each bit: $5AB^2 \times 3AB$ $5AB^2 \times 2... | {"url":"http://mathhelpforum.com/math-topics/44130-factoring.html","timestamp":"2014-04-16T08:11:08Z","content_type":null,"content_length":"35448","record_id":"<urn:uuid:fc6dad58-51c9-4950-8cd9-32cc22fe1850>","cc-path":"CC-MAIN-2014-15/segments/1398223203841.5/warc/CC-MAIN-20140423032003-00456-ip-10-147-4-33.ec2.intern... |

Cauchy criterion for convergence
Cauchy criterion for convergence
A series $\sum_{{i=0}}^{\infty}a_{i}$ in a Banach space $(V,\|\cdot\|)$ is convergent iff for every $\varepsilon>0$ there is a number $N\in\mathbb{N}$ such that
holds for all $n>N$ and $p\geq 1$.
