Sample Learning Goals

For Teachers

This simulation allows for graphical visualisation of a 3D sinusoidal function as a wave.

There are 15 predefined functions that can be inputted from the drop-down menu.

You can also adjust different parameters of the function to see how they affect the wave:

a: Amplitude

b: Frequency

c: Direction (only applicable to functions which allow for change in direction)

p: Simply adjusts the speed of the simulation.

In addition, the x-y plane can be toggled to more easily visualise the positive and negative parts of the wave.
