Sonify points on graph
Notice that there is an increasing mapping between values of the
function and frequencies.
Also notice the use of hiss to indicate negative values.

Sonify a function, investigating limit
What a student might do while investigating a limit:
Play function sonification from the negative side.
Play function sonification from the positive side.
Play function sonification from both sides.
Notice that in the bothside sonification, the lefthand limit is played
through the left speaker, while the righthand limit is played through the
right speaker. Since this limit exists, the two sounds converge at the end
of the clip.

Sonify a derivative, investigating critical points and extrema of function
In this feature, a short tangent segment tracks along the graph of
the function while the graph of the derivative is plotted simultaneously
with the sound.
Again notice the use of hiss to indicate negative values and also a
ping to indicate a zero value of the derivative .

Sonify a definite integral, investigating
net area under a graph
In this feature, the area under the graph is shaded while the graph
of the definite integral is plotted simultaneously with the sound.
Notice that the sound pulses four times in synch with the horizontal axis
tick marks.
