atan2(y, x) is related to atan(y/x), not atan(x/y).

atan2(y, x) is related to atan(y/x), *not* atan(x/y)

* Fix broken table (#269)

* Fix code indentation (#267)

* corrected the output (#276)

* Update collections.array - fsharp .md (#271)

fixed signature for copy function

* fix and consolidate list.xyz2/xyz3 doc for input lists with different lengths (#282)

* Fix escape sequence. (#285)

* Add missing space (#284)

* Fix order of arguments in foldBack lambda (#286)

Running the following in F# Interactive will help explain why I believe this change is necessary:
> List.foldBack (fun elem acc -> printf "elem: %A " elem; elem + acc) [1;2;3;4] 0;;
elem: 4 elem: 3 elem: 2 elem: 1 val it : int = 10
> List.foldBack (fun acc elem -> printf "elem: %A " elem; elem + acc) [1;2;3;4] 0;;
elem: 0 elem: 4 elem: 7 elem: 9 val it : int = 10

The accumulator is the second argument in foldBack (contrary to fold where it is the first).
Positioning the arguments in reverse in an example is a great way to confuse a reader.

This also helps promote the fact that the state and list arguments to the folding function
are in the same order as their lambda counterparts.

Feel free to disagree :-).

* Fix Operators.atan2 description (#287)

atan2(y, x) is related to atan(y/x), *not* atan(x/y)

* Fixed code formatting (#288)

* Corrected prefix minus to prefix plus (#289)

* Added missing line break

Added missing line break to class definition of Microsoft.FSharp.Reflection.UnionCaseInfo

* Removed Missing CustomOperationAttribute Issue #266

* JoinConditionWord was Accidentally removed despite not being duplicated. Fixing this.

* Fix typo in Array2D.init docs

* Document that Map.pick can throw KeynotFoundException

* Update async.startchild['t]-method-[fsharp].md

Specify timeout behaviour

* Fix List.compareWith case

* Update walkthrough-using-visual-fsharp-to-create,-debug,-and-deploy-an-application.md

* Added treatment of null-values, and fixed incomplete text on IFormattable (#301)

The `string` function casts to `IFormattable` internally. The original text only mentioned integer and floating point values, but in fact, there are many more values in the BCL that implement IFormattable. I improved the text to be more precise.

Furthermore, special treatment of `null` was not mentioned, I've added that. Expanded supported platforms, and fixed a typo.

* Update quotations.patterns-module-[fsharp].md (#302)

Thanks @Columpio

* Clarified how ties are resolved (#304)

* Add except to list modules (#305)

The except function added in fsharp/fslang-design#41 doesn't have a doc here.
