Help:

• To render square root, use the sqrt symbol. Example: `sqrt( b^2 - 4ac )`.
• To render powers, use the ^ character. E.g., to render x squared, you would enter ` x^2`.
• You absolutely must use brackets with functions. `sin x` will NOT work! `sin(x)` will work.
• to render integrals, use function `int( x^2, dx, 0, 1)` for definite integrals, `int( e^(-x^2), dx )`, for indefinite integrals.

• To render summations, enter something like `sum( 1/i!, i=0, infinity )`. The first parameter is what you sum, and the second and third are bounds.
• You can use factorial character !. If you say infinity (like in integral bounds or in summation), the infinity character will be painted.
• To plot graphs, enter: `graph( 600, 400, -10, 10, -10, 10, x-2, x^2+3*x)`
• To plot number line, enter: `number_line( 600, -10, 10, -1, sqrt(3), (6.5), (20-13) )`
