To set a wider table , which takes up the whole width of the page ’ s live area , use the environment table * to enclose the table ’ s contents and the table caption . As with a single-column table , this wide table will “ float " to a location deemed more desirable . Immediately following this sentence is the point at which Table 2 is included in the input file ; again , it is instructive to compare the placement of the table here with the table in the printed dvi output of this document .

2.5 Figures

Like tables , figures cannot be split across pages ; the best placement for them is typically the top or the bottom of the page nearest their initial cite . To ensure this proper “ floating ” placement of figures , use the environment figure to enclose the figure and its caption .

This sample document contains examples of . eps and . ps files to be displayable with L ^A TEX . More details on each of these is found in the Author ’ s Guide .

As was the case with tables , you may want a figure that spans two columns . To do this , and still to ensure proper “ floating ” placement of tables , use the environment figure * to enclose the figure and its caption .

Note that either . ps or . eps formats are used ; use the \ epsfig or \ psfig commands as appropriate for the different file types .

2.6 Theorem-like Constructs

Other common constructs that may occur in your article are the forms for logical constructs like theorems , axioms , corollaries and proofs . There are two forms , one produced by

the command \ newtheorem and the other by the command \ newdef ; perhaps the clearest and easiest way to distinguish them is to compare the two in the output of this sample document :

This uses the theorem environment , created by the \ newtheorem command :

Theorem 1 . Let f be continuous on [ a , b ]. antiderivative for f on [ a , b ], then

∫ _b

a f ( t ) dt = G ( b ) − G ( a ).

If G is an

The other uses the definition environment , created by the \ newdef command :

Definition 1 . If z is irrational , then by e ^z we mean the unique number which has logarithm z :

log e ^z = z

Two lists of constructs that use one of these forms is given in the Author ’ s Guidelines .

and don ’ t forget to end the environment with figure *, not figure !

There is one other similar construct environment , which is already set up for you ; i . e . you must not use a \ newdef command to create it : the proof environment . Here is a example of its use :

Proof . Suppose on the contrary there exists a real number L such that f ( x ) lim x→∞ g ( x ) ^{= L .}

Then

[ l = lim f ( x ) = lim gx · ^{f ( x )} ] f ( x )

= lim g ( x )· lim x→c x→c g ( x ) _{x→c x→c} g ( x ) ^{= 0 · L = 0 ,}

which contradicts our assumption that l ≠ 0 .

Complete rules about using these environments and using the two different creation commands are in the Author ’ s Guide ; please consult it for more detailed instructions . If you need to use another construct , not listed therein , which you want to have the same formatting as the Theorem or the Definition [ 6 ] shown above , use the \ newtheorem or the \ newdef command , respectively , to create it .
