You may want to put some math equations in your paper.  If so, you can do so easily by choosing the Insert Plugin -> PB Wiki Magic -> Equation.  LaTex requires you to supply the special characters preceeded with a \ (backslash). 

 

Here are some quick things you may need.

 

Greek Letters

Lower case greek letters are are usually their name.  Lower case \gamma  and upper case gamma \Gamma .  Of course there is your friend and mine \pi .

 

 

Fractions

Fractions are created using the  \frac {numerator} {denominator}.  \frac {d} {dx}  gives you    . 

 

 

Superscripts / Subscripts

 

Superscripts are gotten by a caret (^) and subscript by an underscore (_).  x^2 and a_i yields:

.  You enclose multiple characters with curly braces {}.  So  e to -2x power would be: e^{-2x}   .

 

Vectors

You can make vectors by creating a stack using \stackrel and the \rightarrow.  The vector u   is gotten by \stackrel {\rightarrow } {u}.

 

For example, the formula   is given by \stackrel {\rightarrow } {F} = m \stackrel {\rightarrow }a. 

 

 

Square root, Summation and Intergrals

You can do summation and integral symbols with \sqrt    \sum  and \int  .

 

 

Tying it all together with some commone examples.

Integral from 0 to infinity of f(x) dx: \int _{0} ^{ \infty} f(x) dx .  .

 

The integral from 0 to pi/2 sin of the square root of x dx \int ^{ \frac { {\pi} {2} _{0} } sin \sqrt{x}  dx  

Sum from 0 to n-1 b sub i 2 to the ith power. \sum _{0} ^ {n-1} b_i 2^i  .

 

To make a union, use the \cup   and to make an intersection, use \cap
