= Mathematical Expressions

== Partial Derivatives

$ (partial f) / (partial x) = integral_0^infinity g(x) dif x $

== Quadratic Formula

$ x = (-b plus.minus sqrt(b^2 - 4 a c)) / (2 a) $

== Summation and Products

$ sum_(i=1)^n i = n(n+1)/2 $

$ product_(k=1)^n k = n! $

== Matrix Notation

$ mat(
  1, 2, 3;
  4, 5, 6;
  7, 8, 9
) $

== Limits

$ lim_(x -> infinity) (1 + 1/x)^x = e $
