Math Test
1 Limit
A limit:
limx → ∞f(x),
which should appear as
x → ∞ in italics, and «lim» in plain style. Inlined:
limx → ∞f(x).
And why not, a sum:
∑∞i = 1x,
where the sum’s limits should appear below (
i = 1) and above (
∞) the
∑. Inlined:
∑∞i = 1x. Integral:
∫∞i = 1x.
2 Numeration
Equations can be numbered, like
1↓.
Notice that eq.
2↑ comes after eq.
1↑.
Some equations can also be numbered, even if they don’t have a label.
Other equations that contain * should not numbered, but perhaps aligned:
Some environments allow for multiple labels:
Now a random environment:
y.
3 Parentheses
Some delimiters also taken from the Spanish Lyx User’s Guide. An array:
And an inline array
[
].
There are also big brackets: (a) [b] {c} ⟨d⟩ |e| ⟨f⟩.
Aligned brackets can be present: (toText). One of them may be omitted: toText).
4 Fraction
A big recursive fraction:
1(1 + (11 + (11 + 2x)))
A nice fraction: 5⁄6.
A non-diminishing fraction containing alignments:
11 + (11 + x × 11 + x).
A similar concept is a binomial coefficient:
(A + 1B). It can be prettily presented:
(AB + 1).
5 Roots
A square root:
√3. A more complex square root in a fraction:
1(1 + √2(11 + √2) + √12).
Higher order roots:
3√x + y,
x + 1√Weight. In a fraction:
7⁄8√84xs + 5√(78x + 45y) × √Heightsin(x + 1) + 5.
6 Cases
Used to switch several values.
7 Spacing
The command \raisebox is useful to, surprisingly, raise a little box.
raisedoverloweredand back.
It can also be used just for spacing.
BV.
There are other spacing commands, like \hspace: " ", and \vspace: " ".
8 Fonts
Fonts can be switched on and off.
By default, text in formulae is shown italicized. Variable: meters.
Some font styles. Roman: 1 mathrm. Sans serif: 2 mathsf. Typewriter: 3 mathtt. Bold: 4 mathbf.
Regular text. Normal text: 5 textfm. Literal text: 6 mbox text. Phonetic alphabet: 7 abcde. Regular text can be embedded into formulae: regular text \command \another command \\no spaces allowed.
Units can be shown with or without a magnitude. Without: km. With: 57 km. Fractional units: 20 km⁄h. With a fraction before the units: 3⁄2 km, 716 s.
Some special fonts are supported: ℱ, F, 𝔽, 𝔉.
9 Bye-bye
That’s all folks!
