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) y = x
And also like .
(2) x = 3
Notice that eq. comes after eq. .

3 Parentheses

Some delimiters also taken from the Spanish Lyx User’s Guide. Array:
[
12 2
3 4 × yx
]
And inline array [
a b
c dio
]
.
There are also big brackets: (a) [b] {c} d |e| f.

4 Fraction

A big recursive fraction:
1(1 + (11 + (11 + 2x)))

5 Roots

A square root: 3. A more complex root in a fraction:
1(1 + 2(11 + 2) + 12).

6 Cases

Used to switch several values.
y = 
x i = 0, 
x + 1 i < 3

7 Bye-bye

That’s all folks!
