The basics of latex notation are
^ for superscript
_ for subscript
{} for grouping
\sum for summation
\log for logs
\Omega for upper case greek letter omega
\alpha for lower case greek letter beta
\int for integral.
See http://www.codecogs.com/latex/eqneditor.php for a playground where you
can test things.
Try this, for instance,
F(x,y)=0 ~~\mbox{and}~~
\left| \begin{array}{ccc}
F''_{xx} & F''_{xy} & F'_x \\
F''_{yx} & F''_{yy} & F'_y \\
F'_x & F'_y & 0
\end{array}\
right| = 0
