~~NOTOC~~ ====== Math Syntax Help====== The usage of the commands for math syntax is indicated by "m" between angle brackets as shows in the sample code below:


x in bbR \ { 1; 2 }

===== Typical commands ===== x+y : x+y \\ x-y : x-y \\ x*y : x*y \\ x/y : x/y \\ x^y : x^y \\ x_y : x_y \\ x<>y : x<>y \\ x>y : x>y \\ x>=y : x>=y \\ xx \\ x<=y : x⇐y \\ (x) : (x) \\ {x} : {x} \\ ===== Space ===== a~b : a~b \\ ===== Greek ===== alpha : alpha \\ beta : beta \\ gamma : gamma \\ delta : delta \\ epsilon : epsilon \\ varepsilon : varepsilon \\ zeta : zeta \\ eta : eta \\ theta : theta \\ vartheta : vartheta \\ iota : iota \\ kappa : kappa \\ lambda : lambda \\ mu : mu \\ nu : nu \\ xi : xi \\ pi : pi \\ varpi : varpi \\ rho : rho \\ varrho : varrho \\ sigma : sigma \\ varsigma : varsigma \\ tau : tau \\ upsilon : upsilon \\ phi : phi \\ varphi : varphi \\ chi : chi \\ psi : psi \\ omega : omega \\ Gamma : Gamma \\ Lambda : Lambda \\ Sigma : Sigma \\ Psi : Psi \\ Delta : Delta \\ Xi : Xi \\ Upsilon : Upsilon \\ Omega : Omega \\ Theta : Theta \\ Pi : Pi \\ Phi : Phi \\ ===== Symbols ===== infty : infty \\ in : in \\ notin : notin \\ forall : forall \\ exists : exists \\ notexists : notexists \\ partial : partial \\ approx : approx \\ pm : pm \\ inter : inter \\ union : union \\ ortho : ortho \\ parallel : parallel \\ backslash : backslash \\ prime : prime \\ wedge : wedge \\ vert : vert \\ lbrace : lbrace \\ rbrace : rbrace \\ circ : circ \\ varnothing : varnothing \\ subset : subset \\ notsubset : notsubset \\ cdots : cdots \\ vdots : vdots \\ ddots : ddots \\ ===== Arrows ===== left : left \\ right : right \\ leftright : leftright \\ doubleleft : doubleleft \\ doubleright : doubleright \\ doubleleftright : doubleleftright \\ nearrow : nearrow \\ searrow : searrow \\ ===== Sets ===== bbR : bbR \\ bbN : bbN \\ bbZ : bbZ \\ bbC : bbC \\ ===== Roots and Limits ===== sqrt{a} : sqrt{a} \\ root{n}{a} : root{n}{a} \\ lim{a}{x} : lim{a}{x} \\ ===== Big Operators ===== int{a}{b}{x} : int{a}{b}{x} \\ doubleint{a}{b}{x} : doubleint{a}{b}{x} \\ tripleint{a}{b}{x} : tripleint{a}{b}{x} \\ oint{a}{b}{x} : oint{a}{b}{x} \\ sum{a}{b}{x} : sum{a}{b}{x} \\ prod{a}{b}{x} : prod{a}{b}{x} \\ bigcup{a}{b}{x} : bigcup{a}{b}{x} \\ bigcap{a}{b}{x} : bigcap{a}{b}{x} \\ ===== Delimiters ===== delim{[}{x}{]} : delim{[}{x}{]} \\ delim{]}{x}{]} : delim{]}{x}{]} \\ delim{[}{x}{[} : delim{[}{x}{[} \\ delim{]}{x}{[} : delim{]}{x}{[} \\ delim{lbrace}{x}{rbrace} : delim{lbrace}{x}{rbrace} \\ delim{|}{x}{|} : delim{|}{x}{|} \\ delim{vert}{x}{vert} : delim{vert}{x}{vert} \\ ===== Matrix ===== Syntax : matrix{num of lines}{num of columns}{first_element … last_element} matrix{2}{3}{a b c d e f g} : matrix{2}{3}{a b c d e f g} \\ ===== Tabular ===== Syntax : tabular{lines description}{columns description}{first_element … last_element}\\ lines : sequence of 1 (draw the horizontal line) or 0 (don't draw the horizontal line) - the length of the sequence=num of lines+1\\ columns : sequence of 1 (draw the vertical line) or 0 (don't draw the vertical line) - the length of the sequence=num of columns+1\\ tabular{111}{1111}{a b c d e f g} : tabular{111}{1111}{a b c d e f g} \\ tabular{1001}{101}{1 2 3 4 5 6} : tabular{1001}{101}{1 2 3 4 5 6} \\ ===== Constructions ===== vec{express} : vec{express} \\ {express}under{foo} : {express}under{foo} \\ {express}over{foo} : {express}over{foo} \\ overline{express} : overline{express} \\ underline{express} : underline{express} \\ hat{express} : hat{express} \\
