Superscript and subscript
superscript and subscript ^ and _ are used, for example, \ (x_i ^ 2 \) represents the:.
By default, the subscripts only works for the next group. I.e., a single character, or group content using {..} wrapped up. If \ (10 ^ 10 \) indicates that the \ (10 ^ {10} \) is. Meanwhile, braces also to eliminate ambiguity, such as x ^ 5 ^ 6 will get an error, braces must be used to define the binding ^, such as \ (^ {X ^}. 5. 6 \) : or \ (X 5 ^ 6 ^ {} \) :
Brackets
Parentheses and square brackets
use the original (), [] to as \ ((2 + 3) [4 + 4] \) :
Use \ left (or \ right) that the symbol size and fit adjacent formula (this statement applies to all types parentheses), as \ (\ left (\ FRAC {X} {Y} \ right) \) :
braces
since the braces {} are used for the packet, it is necessary to use a large {and} represents brackets, you can also use \ lbrace and \ rbrace to represent. The \ (\ {a \ * b \}: a \ * b \) or \ (\ lbrace a \ * b \ rbrace: a \ * b \) FIG.
Angle brackets
Distinguish the less than and greater than, the use of \ langle and \ rangle a left bracket and a right angle brackets. Such as \ (\ langle x \ rangle \ ) said:
Rounding the
use \ lceil and \ rceil FIG. Such as, \ (\ lceil the X-\ rceil \) :.
Rounding the
use of \ lfloor and \ rfloor FIG. Such as, \ (\ lfloor the X-\ rfloor \) :.
Summing and integration
sum
\ sum summation notation is used to indicate that the subscripts indicate summation limit, superscript indicates the upper limit. Such as:
\ (\ sum_. 1} = ^ {n-R & lt \) represents:.
\ [\ sum_ {r = 1 } ^ n \] represents:
Integral
\ int integral sign to represent, in the same manner that the vertical scale represents upper and lower limits of integration. Such as, \ (\ the int_. 1} = {R & lt ^ \ infty \) :.
Multiple integration also use int, represents integral derivative by the number of i:
\ (\ Iint \) : \
(\ iiint \) : \
(\ iiiint \) :
multiplicative
\ (\ Prod {A + B} \) , the output :.
\ (\ prod_. 1 = {I} ^ {K} \) , output:
\ [\ prod_ {I} = ^ {K}. 1 \] , output:
Other
like this there are symbols,
\ (\ Prod \) : \
(\ bigcup \) : \
(\ bigcap \) : \
(Arg \, \ max_ C_K} {\) : \
(Arg \, \ min_ {C_K} \) : \
(\ mathop {argmin} _ {C_K} \) : \
(\ mathop {the argmax} _ {C_K} \) : \
(\ max_ {C_K} \) : \
(\ min_ {C_K } \) :
fraction and radical
fraction
The first, using \ ab & frac, \ frac after acting thereon two groups a, b, results. If you are not the numerator or denominator of single characters, use {..} grouping, such as \ (\ frac {a + c + 1} {b + c + 2} \) FIG.
Second, using \ over to separate the front and rear portions of a group, such as {a + 1 \ over b + 1}:
