1 The graph command

The easiest way to include an interactive Desmos graph is to use the \graph command. Unfortunately, the \graph command doesn’t draw a graph in the PDF, rather, it states (in words) that a graph is produced. That is, 

\[
  \graph{x^2,x^3}
\]

produces

\[ \graph {x^2,x^3} \]

in the PDF. Online, the command produces something like this:

There are a number of options concerning the function being graphed: 

\graph{x^2,x^3}                     %% just x^2 and x^3
                                    %%
\graph{x^2                          %%
\left\{ 1 \leq x \leq 10 \right\}}  %% restricted domain
                                    %%
\graph{\sin(x) \left\{x<0\right\},  %%
2x \left\{ x>=0 \right\} }          %% piecewise
                                    %%
\graph{r=\theta}                    %% polar

While the code above modifies the function being graphed, there are also several options for the display of the graph.

Optional arguments for \graph

xmin, ymin, xmax, ymax

These set the size of the viewing window with \graph[xmin=-5,xmax=5,ymin=-5,ymax=5]{y=x^2}.

panel

Determines if the panel is shown with \graph[panel]{y=x^2}.

xAxisLabel, yAxisLabel

Gives the axes labels with \graph[xAxisLabel="time", yAxisLabel="distance"]{y=x^2}.

hideXAxis, hideYAxis

Hides the axes with \graph[hideXAxis=true, hideYAxis=true]{x^2}.

hideXAxisNumbers=true, hideYAxisNumbers=true

Hides the tick marks on the axes with \graph[hideXAxisNumbers=true, hideYAxisNumbers=true]{y=x^2}.

polar

Shows polar grid lines with \graph[polar]{y=x^2}.

\[ \graph {x^2 \left \{ 1 \leq x \leq 10 \right \}} \graph { \sin (x)\left \{x<0\right \}, 2x\left \{ x>=0 \right \} } \]

2 Desmos, Desmos 3D, and GeoGebra

If you require further features from Desmos, you can sign up for an account and include your worksheets using the syntax \desmos{ID}{width}{height}, where ID is the widget ID and width and height are the dimensions (in pixels) you want the embedded widget to have. 

\begin{center}
\desmos{zwywds7med}{800}{600}
\end{center}

which renders as:

The syntax for Desmos 3D is similar. Use \desmosThreeD{ID}{width}{height}, where ID is the widget ID and width and height are the dimensions (in pixels) you want the embedded widget to have. 

\begin{center}
\desmosThreeD{bb4exrhrl3}{800}{600}
\end{center}

Seen here:

You can also use GeoGebra. Embed the widget using the syntax \geogebra{ID}{width}{height}, where ID is the widget ID and width and height are the dimensions (in pixels) you want the embedded widget to have. 

\begin{center}
\geogebra{XC3FXUdJ}{800}{600}
\end{center}

While we cannot get data from these sorts of interactives directly, the clever author can ask questions that use the interactive to find a solution.
