An Algorithm is a step-by-step solution to a problem.
It is like a cooking recipe for mathematics.
Example: one algorithm for adding two digit numbers is "add the units, add the tens and combine the answers"
Long Division is another example of an algorithm: if you follow the steps you get the answer.

(which are fully connected) and the connectivity of the... | {"url":"http://dwave.wordpress.com/category/learning-to-program-the-d-wave-one/","timestamp":"2014-04-21T07:18:56Z","content_type":null,"content_length":"194856","record_id":"<urn:uuid:73bbd136-3f8c-4a5d-ab31-5e70e0029608>","cc-path":"CC-MAIN-2014-15/segments/1397609539665.16/warc/CC-MAIN-20140416005219-00272-ip-10-147... |

How do you derive the formula of S csch(x)(dx)=ln (tanh (x/2)) +C ?

How do you derive the formula of S csch(x)(dx)=ln (tanh (x/2)) +C ?
The integrand can be transformed to functions of tanh (x/2) by first observing that sinh 2A = 2sinh A cosh A,
from which
