K

kappa

$$\kappa$$ gives \kappa
L

lambda (lower case greek letter)

$$\lambda$$ gives \lambda

Lambda (upper case greek letter)

$$\Lambda$$ gives \Lambda

\frac{success}{problem}=~\unitlength{.6}~\picture(100){~~(50,50){\circle(99)}~ ~(20,55;50,0;2){+1$\hat\bullet}~~(50,40){\bullet}~~(50,35){\circle(50,25;34)}~ ~(50,35){\circle(50,45;34)}}

left only brace

  • Syntax: \left{...\right.  (note the dot at the end!)
  • Ex.: $$f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.$$ gives

f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.

(\rm~something switches to roman style)

less than

$$<$$   is

less than or equal

$$x\le~y$$ or $$x\leq~y$$ gives

x\le~y

math spaces

List of predefined spaces:

Math Spaces
CommandExampleResult
\, (smallest predefined)$$a\,b$$a\,b
\:  (second smallest predefined)$$a\:b$$a\:b
\;  (third smallest predefined)$$a\;b$$a\;b
\/  (avoiding ligatures)$$V\/A$$ instead of $$VA$$V\/A instead of VA
\quad  (space of current character set size)$$a\quad~b$$a\quad~b
\qquad  (double space of current character set size)$$a\qquad~b$$a\qquad~b
\_ (where _ is blank!)

$$a\ b$$

(whereas $$a\b$$ is not a valid filter expression since the blank space is missing; it is recommended to use the tilde ~ instead of the simple whitespace)

a\ b

\hspace{n} ,where n positive integer (= n Pixels)

$$a~\hspace{30}~b$$

$$a~\hspace{15}~b$$

$$a~\hspace{2}~b$$

$$a~\hspace{1}~b$$

a~\hspace{30}~b

a~\hspace{15}~b

a~\hspace{2}~b

a~\hspace{1}~b

\unitlength{m}\hspace{n}, changes the default unit length (m=1px) to be applied

$$a~\hspace{2}~b\unitlength{10}~\hspace{2}~c$$

(second space is 10x2=20px)

a~\hspace{2}~b\unitlength{10}~\hspace{2}~c

Note: Simple blank spaces and tildes (~) are ignored by the TeX filter and don't produce any space. You must use one of the defined math spaces to get a visible (extra) space.

mathematics expression

  • A valid expression inside the $'s is rendered as mathematics in an inserted gif image.
  • Ex.: $$x=y^2$$ creates 

x=y^2
