Quick Language Guide

Limit

{{ lim( f(x), x, l ) }}
  f(x) -> a function of x (e.g. x^2+2*x+1)
  x -> the variable that approaches the limit
  l -> the limit we are approaching

Sum

{{ sum( f(x), x, a, b ) }}
  f(x) -> a function of x
  x -> the variable that is changed
  a -> lower bound of sum
  b -> upper bound of sum

Product

{{ product( f(x), x, a, b ) }}
  f(x) -> a function of x
  x -> the variable that is changed
  a -> lower bound of product
  b -> upper bound of product

Integral

{{ integral( f(x), x, a, b ) }}
  f(x) -> a function of x
  x -> the variable in which we are interested
  a -> lower bound of integration
  b -> upper bound of integration

Choose

{{ choose( n, k ) }}
  n -> from n elements
  k -> choose k elements

Divide

{{ divide( n, d ) }}
  n -> numerator
  d -> denominator

Chaining Commands

  {{ lim( sum(x^2, x, 1, k), k, infinity ) }}
